How many moles of B will react with 2.00 moles of A?

How many moles of C are produced when 2.00 moles of A react?


Fe2O3 + 3 H2 → 2 Fe + 3 H2O
How many moles of H2 are required to react with 9.73 moles of Fe2O3?

When dealing with calculating the number of mols of different substances in an equation, always look at the coefficients ((when doing this, it's always what you want/what you have)). 

How many mols of B will react with 2.00 mols of A?

2.00(2/3)= 1.33 mols B

How many mols of C are produced when 2.00 mols of A react? 

2.00(1/3)= 0.66 mols C


9.73 mols Fe2O3 x 3/1=29.19 mols H2
