| 1. The equation for the reaction of magnesium with dilute sulfuric acid is:
Mg + H2SO4 = MgSO4 + H2 ↑;
2. find the chemical amount of hydrogen:
n (H2) = V (H2): Vm = 33.6: 22.4 = 1.5 mol;
3. Determine the amount and calculate the mass of magnesium:
n (Mg) = n (H2) = 1.5 mol;
m (Mg) = n (Mg) * M (Mg) = 1.5 * 24 = 1.5 * 24 = 36 g.
Answer: 36 g.
