what mass (in g) of P2O5 would be produced if 0.590 moles of H2O are produced?

Answer:
grams P₂O₅ produced = 27.9 grams
Explanation:
2H₃PO₄ => P₂O₅ + 3H₂O
for 0.590 mole yield of H₂O there will also be a yield of 1/3(0.590 mol P₂O₅) = 0.197 mol P₂O₅
gram mass yield of P₂O₅ = (0.197 mol P₂O₅)(142 g/mol) = 27.9 grams P₂O₅
