Stoichiometry help..
P4O10+6H20-----4H3PO4

1) Calculate the theoretical yield if 100 grams of P4O10 reacts with 200 grams of H2O.
2) If the actual mass recovered is 126.2 g, what is the percent yield?

Please help, thank you!

on 1): the equation says that 1 mol of P4O10 needs to react with 6 mol of H2O. so the number ratio needs to be 1:6. are the reactants in this ratio? if not, which one limits the amount of product that we get?
