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 P 4 O 10 = (4 x 30.97) + (10 x 16.00) = 283.88 g mol -1 . Moles of P 4 O 10 = 5.00/283.88 = 1.76 x 10 -2 ...
