Percent Yield Made Easy: Stoichiometry Tutorial Part 4

This is a whiteboard animation tutorial that demonstrates how to identify the actual yield of a chemical reaction and how to calculate the theoretical yield and percent yield of a chemical reaction.
Please consider supporting me on Patreon:
/ ketzbook
The actual yield is the amount of product that is actually produced and isolated from a chemical reaction.
The theoretical yield is the amount of product that could be produced if the reaction worked perfectly. In order to determine the theoretical yield, you will need to perform a stoichiometry calculation (typically grams to grams).
The percent yield tells you how well the reaction worked. It is the actual yield divided by the theoretical yield times 100%.
This is the fourth tutorial in my stoichiometry series.
My goal is to make chemistry easier ;)

Thank you for taking your time in breaking it down in a way that I can understand. It makes it easier to understand when you use everyday products as visual learning tools. Chemistry can be so abstract at times.

You're very welcome!

It's normally less than 100% because the reaction might be incomplete, there may be side reactions, product loss when purifying or may be spilled or blown away

[@shanialenae1008]

percent yield is normally less than 100% because different side reactions may occur or the products may get lost | 00805 |

00803] Percent yield tells how much a specific chemical reaction actually yields compared to it's theoretical potential.

[@cierrasouthard6532]

the percent yield is normally less than 100% because the reaction could be incomplete and different side reactions going on as well. product could be lost through the reaction and could affect the percent yield. 00823

[@Ilyff]

saving me before my exam tmmrw

[@meganperdue2865]

Percent Yield tells you how well the reaction worked; the actual yield divided by the theoretical yield times 100; 00415

[@tariqmasih6986]

Please make video on soda glass and opal glass

[@OGDEN25]

God bless you

[@shelovesRH]

the percent yield is basically the mass of the actual yield over the mass of the theoretical yield multiplied by 100

[@luzzacariaz7021]

the percent yield is normally less than 100% because the reaction might be incomplete, there may be side reactions, product loss when purifying or may be spilled or blown away, 00611

[@rebeccaarpie9184]

ID:00404 If the percent yield is 250%, that means that there is a mistake and needs to be fix. This results form the actual yield being larger than the theoretical yield and this physically cannot happen. A calculation or measuring mistake must have occurred.

[@hueyt3323]

Percent yield conveys the accuracy of the reaction. Actual yield/theoretical yield x100 = percent yield.

[@alanafox7866]

It's recoiling to compare what you do vs the institutions. Being sincere & generous to "the system", I estimate 1 of your minutes is more valuable than 1 of their hours. At this point I'm nerding out and watching for fun, though it's put a thorn in my side... where could I be if such clean and clear content were available in my youth... The Kurzgurzat (spelling this wrong) channel gives me a similar feeling. Anyway, just venting a Well Done to the void. Cheers!

[@ketzbook]

Thanks, I'm glad this helped! And it's an honor to be compared with Kurzgesagt; I love Kurzgesagt!

[@AMysteryGhost]

Nothing can save me now. This video was my last shot

[@danez199]

00123, percent yield is usually less then 100% because the theoretical amount is usually more then the actual yield

[@okpala1586]

SO HELPFUL OMG

[@rebeccamerritt6001]

Percent yield is how well the reaction worked, it is the actual yield divided by the theoretical yield multiplied by 100 00115

[@daejahjackson-powell7096]

Percent yield is normally less than 100% because it could be an incomplete reaction, a side reaction, product could've been blown away or spilled, product sticks to the container, or product was lost when purifying., 00811

Actual yield is the amount that is actually collected during a reaction, 00607

[@gio7964]

wow I actually get it

[@rachaelbreneman8572]

a percent yield shows how good or efficient your reaction is

[@rat_coder]

because there are usually impurities and undesirable reactions 00205

[@MAndy-sw8rb]

Compares the actual yield and the theoretical yield to show how well the experiment worked in a percent don't forget to times by 100, 00403

[@erykbluto2468]

Theoretical yield is taken from what you have and made with the most amount, 00702

[@organic2840]

how to write organic reactions in video scribe? please guide me

[@ketzbook]

There are some Videoscribe instructional videos on youtube to get you started. If you want to do something like a reaction mechanism, you will have to draw it in ChemDraw or some similar program, then save the individual parts as tiff, png, or jpg, and import them into your Videoscribe. If you want to get a better drawing effect, you will need to convert it to svg, but that may not be worth the effort. It is a long process.

[@y2k513]

How much of the product that is made without any thing added or changed, 00707

[@onyeagusimarycynthia3138]

Can the actual yield be equal to the theoretical yield

[@asdf7711]

Yes, but unlikely. It's theoretically possible to get 100% yield if actual yield = theoretical yield.

[@hannahohara5969]

Actual yield is what is physically made or product produced, 00213

[@ZioTrickz]

Pretty much how well the reaction or experiment went., 00821

[@kaylynndick9344]

Percent yield tells me how well the solution was effective, 00409.

[@kaiyahall6934]

Theoretical yield is how much the product is when its combined

[@kaitlinhitchens679]

percent yield is normally less then 100% because the theoretical amount is usually more then the actual yield. 00111

[@Rubester11]

00414 Theoretical yield is the most amount you can make

[@rhyno17]

Actual yield is amount of product actually made in a reaction

[@RYanimayyyyy31]

Theoretical yield is simply the greatest possible amount of what you can make with what you have. 00814

[@jordin407]

00815: The percent yield tells you how successful your work has been at producing the desired product

[@shaunkelly6224]

There is no actual yield on my question. Can we find it out of scratch?

[@ketzbook]

is it a lab question?

[@esthersibeso5581]

A different method we always use to calculate theoretical yield gave me 3.84g and now I'm all confused

[@shawnmitchell7518]

Purity elements and check calculations, 00816

[@alisawarren2096]

The ratio of the actual yield to the theoretical yield. How close you are to the 100% mark. 00609

[@tiapersolio322]

Check your calculations/measurements and make sure your product is pure, 00416

[@ashleymartinez2466]

Theoretical yield is the most of something that you can make with however much you have. 00114

Incomplete reaction or error

Theoretical yield: how much a product is when combined

[@MiguelSantiago-tr4ff]

You can't get the full amount out normally of what you put in, 00217

[@colehatton9784]

the percent yield should be less then 100% if its over 100% then side reactions and other things might occur so you might want to go over your calculations again #008334

[@deniserobles9253]

a calculation or a measurement error has occurred within the process, 00216

80%, 00206

[@shanialenae1008]

percent yield tell me how much a actual yield compare to a theoretical yield. 00809

[@marisoldeleon3735]

Actual yield is the amount of product that is actually made, 00801

[@sierrahfindeison3092]

The percent yield should be less than 100% if it is 250% an error has occurred and you should re-do the problem, 00110

[@justinalloway1405]

Actual yield is the amount of a product that can be made of an isolated chemical

[@kirashort1895]

80%, 00218

[@johnriovelasco5617]

molar mass of 3O2 is 32.0? I thought it was 35

[@ChemSimplified]

It's 32.0 since there are 2 oxygen atoms, so 2 x 16.00 = 32.00 g/mol

[@clairetrimble8439]

Actual yield is the amount that's actually produced, 00419

[@reaganlittle6431]

the actual yield is the how much product is actually made, 00813
