Mass of magnesium compound
WebSo 1 mole of magnesium produces 1 mole of hydrogen molecules, i.e. 24.4 litres = 24, 400 cm 3 of hydrogen gas. If 0.03 g of magnesium produces 30.5 cm 3 of hydrogen gas, the mass of magnesium needed to produce 24, 400 cm 3 of hydrogen gas = 24, 400 × 0.03 / 30.5 = 24 g. So the relative atomic mass of magnesium is 24.8.
