You are given
130 grams of H20 and 18 grams of H2. You are required to get the theoretical
yield of H2O. Before anything else, you should know the chemical equation of
H20 and H2. The balanced chemical reaction is 2H2 + O2 -> 2H2O. The molar
mass of H2O is 18 grams per mole and the 2 grams per mole for H2.
18g H2 (1 mol
H2/2 g H2)(2 mol H2O/ 2 mol H2)(18 g H2O/1 mol H2O) = 162 g H2O
Thus the theoretical
yield for 18g H2 is 162g H2O.
