From the balanced equation, 1 mol Zn produces 1 mol H2 (mole ratio Zn:H2 = 1:1).
So 3.0 mol Zn × (1 mol H2 / 1 mol Zn) = 3.0 mol H2.
Answer: 3.0 moles of hydrogen (assuming HCl is in excess).
So 3.0 mol Zn × (1 mol H2 / 1 mol Zn) = 3.0 mol H2.
Answer: 3.0 moles of hydrogen (assuming HCl is in excess).
