Stoichiometry with Mass: Stoichiometry Tutorial Part 2

This is a whiteboard animation tutorial of how to solve Stoichiometry problems involving mass.
For a limited time, get $200 cash if you qualify! Check out:
www.referyourchasecard.com/18...
Because amounts MUST be converted to moles before converting between chemicals, stoichiometry problems involving mass are muti-step calculations. This video explains how stoichiometry with mass works for an everyday problem involving food and then goes on to show how to solve a 3-step mass-mass stoichiometry problem for a chemical reaction. This is my second tutorial in the series.
Steps for a Mass-Mass Stoichiometry Problem:
1) Write down the balanced chemical equation
2) Calculate the molar masses of the chemicals
3) Convert mass to moles of what you know
4) Convert moles of what you know to moles of what you want to know
5) Convert moles to mass of what you want to know
My goal is to make chemistry easier ;)

It’s amazing how a roughly 6 minute video can explain this stuff better than weeks of school work on it

This is really helping with my understanding ! Explained better than my lecturer. Ty.

I really appreciate that you explain why each step is done the way it is. My biggest problem in math is not being able to set up equations because I never understood why certain equations are set up the way that they are. This video has helped me to understand, and I could not be more happy about it! Thank you!!!!!!

the conversion factor between moles and grams is a molar mass is the atom or molecule. 00104

[@brookeparker7332]

the conversion factor between one chemical and another is the weight of the reactant that you is given and then put the reactant that you are loving for on top it can also be the balanced equation, 00214

[@marisoldeleon3735]

1.) Converting from one chemical to another you must use the units miles and grams 2.) I learened that to convert moles to miles you divide by the amount of elements itself. 00801

00815: 5 Steps for stoichiometry are write a balanced equation, determine your known and unknowns, covert mass to moles, convert moles to mole (ratio), and convert mole to grams

[@MAndy-sw8rb]

[@srimanasa6479]

This is really helpful 👍 Thanks a lot!! But to make the calculation easy,by reducing steps, there's another method to calculate which gives the same answer i.e, 100g of H2O×16g of O2(considering only one molecule)/18g of H2O =88.8 g of O2. Hence,the answer is same can this method be applied too?

[@harinivasan9609]

Man , you're making it a lot harder

[@ketzbook]

harder than....what? The math involved for any method will always be the same. The main difference between methods is the organization of the numbers and units. What I presented in this video is the standard method, and frankly chemists of all levels use this because it minimizes mistakes (people make mistakes frequently when they try to just multiply this and divide that in their calculator without writing it down). In the third video in my series, I highlight several tricks and patterns that make it easier to remember this set up.

There are more steps and conversions when mass is involved in stoichiometry, therefore you must convert mass to moles, then the moles of one chemical to the moles of another, then finally convert moles to mass. 00421(Elijah Tull)

[@hannahohara5969]

You can not convert from grams of one thing to another directly because it is a ratio of the mole. Once you convert into moles, you can multiply or divide and finally convert to grams again with your conversion factor, 00213

Thanks a lot, but, the example of hotdogs is somehow difficult to understand for students. Secondly, when you make the mass to mole conversion, no need for all this complication, n=m/M, just get the number of the moles, do the Stoichiometry ratio to get the number of moles of the second molecule, and repeat n=m/M to find the mass and that’s all.
