Question: how to calculate percent yield of hydrogen gas?
Answer: Answer: Use the relationship: Percentage Yield Actual Yield (mol) Theoretical Yield (mol) = × 100 % Substitute values and solve: Percentage yield of hydrogen gas = (1.524 × 10 -3 mol H 2 / 1.571 × 10 -3 mol H 2 ) × 100 % = 97.0 % Check the calculations.
