How to Calculate Percent Yield and Theoretical Yield The Best Way - TUTOR HOTLINE

[@melissamaribel]

Hope this video helped! I've also made the perfect set of notes for finding percent yield, theoretical yield, limiting reactants, and more. Get them here melissa.help/limreactnotes

[@bchandrax]

May u pls teach how to calculate percentage purity

[@aalayjawashington]

i love you

[@christabellechabala2540]

It most definitely did. I've watched from many other tutor's I still couldn't get it 🥺 but with you I've found it really easy💖

[@jaredburke3891]

I thought maybe pre med wasn't for me. Then after watching your videos I learned that I needed to just be taught in a different way. Thank you so much you're a godsend.

[@melissamaribel]

Exactly! If it doesn't make sense, it just means you need to learn it a different way. Keep going Jared 👍

[@LiXiaoChunSpadeDuke-ish]

This comment gives me hope. My chemistry teacher is doing a classroom experiment where she teaches us things after the HW and test, and the difficulty from it and the confusion even with KZbin was making me wonder if I'm not cut out for my major. Hopefully I can have a turn around!

I dont like chemistry but youve made it bearable. And I passed my chem class so thats awesome thank you so much

ugh thanks for saving our grades queen 💗😌✊

Anytime! 💕

[@sarahialbornoz1518]

you honestly saved me. I’ve been looking for the right video to help find the percent yield of a reaction where part of the reaction uses an excess. this video was a perfect explanation on how to approach the work. thank you so much!

[@chloewilliams3275]

distanced learning has been really tough and my chem teacher is having a hard time adjusting. meanwhile, I as a student, am expected to be working at 100%. Your videos have helped me so so so much. Thank you from the bottom of my heart ♥️

[@OTStudentFP]

Thank you for making this channel, life CHANGING for someone who is an auditory learner and also needs step by step instruction. LOVE YOUR GRAPHS, I don't get bored listening to you.

[@azlynruby3920]

Really wishing I found your videos earlier on in the semester haha and not the night before my final. You explain everything really well. Thank you!! 💕

This was the absolute best video EVER!!!! I love this layout and that you're using actual typed out problems instead of the paper clipping, which truly confuse this girl lol. LOVE THIS, PLEASE PLEASE KEEP EM COMING!! LOVE YOU!!!!

Thank you so much Giana!

[@akashayaqub7175]

This is a great resource and it's very helpful indeed. I just don't understand why the 0.374kgCH4 wasn't used (12:47) if it was one of the givens. The actual yield, as mentioned in the video, was .983kgCO2 and I am not sure how you knew .983kgCO2 was the actual yield instead of .374kgCH4 being the actual if it makes sense. Thanks for all that you do!

[@carolineisonline3971]

i have my last chem test tomorrow...i had no idea what was happening before i binged your videos, thank you so much for being so clear and thorough! :)

Wouldn't the theoretical value be 1026? How do we jump from 1025.5 to 1030? Don't we round up to the next number which would be 1026. Please explain.

This is so amazing. My college professor assigns your videos as homework and this is the first "tutor hotline" one I've seen. I love how aesthetic this video was! I also got to visit your website for the first time, and I want absolutely everything that is on there!!

[@ebenburger111]

If I understand this correctly, there's a very simple way to get an average extraction yield. Weigh the Original dried ingredient you'd like to extract. Infuse your dried substance and filter. Now dehydrate the remainder Fibrous content to get rid of most of the water - comparable to its original state, and Weigh it again. The difference in weight before and after the infusion of the dried matter will show you how much extracted content you now have mixed within your liquid. For example, if the dried coffee was 100g before extraction, and after filtration and dehydration is 60g, the total dissolved/extracted content is 40g.

[@hiiamchieska8260]

THANK YOU SO MUCH ☺️

[@loveofaflower5486]

Excuse me but, when calculating theoretical yield, would you not coincided the second component “O2 and 2H2O” since it has a smaller value of 528.211? I’m a bit confused with this topic…please can you take the time to explain?

[@STP31]

Thank you soo much teacher

[@hindmawoud5320]

You are genius teacher I respect you a lot

[@ricecum5814]

do we multiply the coefficients with the subscript or add them

[@jiselleleann1610]

Chemistry is so confusing, but after I've watched your video about chemistry, goshh it's not that hard as I think of, I just need to understand it. Thanks to youu.❤️

[@giselle201]

Hi! I might have missed when you said it, but just to be sure, you picked 0.983 kg instead of 0.374 kg because its bigger, right?

[@AwaisKhan-mh6cd]

u deserve more subscribe about 1M tbh love ur effort

Ahh I wish all the chemistry teachers would have been like Melissa

[@Ivan-gt4ln]

Is limiting reactant the same as theoretical yield?

[@Ivan-gt4ln]

nevermind lol thanks

[@nigiasb8709]

nice explanation!

[@jeddaaah]

nice, what software are you using for explanation? what device is it

[@naomygonzalez4930]

Hello Meliss! No one is class could figure this out, but thought maybe you could. We did a precipitate lab and we mixed magnesium hydroxide and hydrochloric acid and CO2 was formed. We don’t know why this reaction would happen.

[@melissamaribel]

Were you guys testing for carbonate in your sample? If acid reacts with carbonate then CO2 is produced. I'm gonna need a little more info on your lab to know exactly what's going on. What was the purpose of the lab or procedure, what was the initial sample you used etc.

[@cyrussneilmancia4625]

If 5.25 g SO2 reacts with excess of CaCO3 and O2, how many grams of CaSO4 are formed?

[@bernicelin8045]

Why did u divide by the molar mass

[@Userraw674]

why did you multiply oxygen by 16 for co2?

[@leszyg6082]

You're the best!

[@olaalmaarufiz5116]

Why did you chose CO2 specially to the theoritical yield?💕

[@adt4025]

Is it possible that a question will end up with a % yield higher than 100? Idk how to fix it.

[@ibireconditum6466]

late to answer but just in case anyone sees this and is wondering the same thing, the answer is no that is not possible. The law of conservation of mass says matter cannot be created nor destroyed and that would be creating it :)

[@learnwithberryafaithfulser5565]

I love lovelovee your channel . It is so perfect! :)
