I’m not sure how to do this, please help. It’s a mole to mole stoich worksheet.

4.05 mol O2, 15.36 mol H2O

Explanation:

I can answer each question individually if you post them individually.

2a. 3.24 mol NH3 * (5 mol O2 / 4 mol NH3) = 4.05 mol O2

2b. 12.8 mol O2 ( 6mol H2O/ 5 mol O2) = 15.36 mol H2O

Essentially what I did was dimensional analysis. Multiplying in a way that the units cancel out so the only thing remains is what each question asks for.
