The percent yield is 74.4 %.

Fe₃O₄ + 4H₂ → 3Fe + 4H₂O

First, calculate the theoretical yield of H₂O.

Theor. yield = 0.112 g H2×1 mol H22.016 g H2×4 mol H2O4 mol H2×18.02 g H2O1 mol H2O=1.001 g H2O

Now calculate the percent yield.

% yield = actual yieldtheoretical yield×100%=0.745 g1.001 g×100%=74.4%
