What is the limiting reagent and thus the mass of product for the reaction: P4O10 + 6H2O --> 4H3PO4 if 5.00 g of P4O10 react with 1.50 g of water?

1) Determine the moles of each reactant and thus the limiting reagent:# moles= mass (g)/M_{r .}M_r of P₄O₁₀ = (4 x 30.97) + (10 x 16.00) = 283.88 g mol
