Calculate the mass of magnesium sulfate obtained by the action of sulfuric acid on magnesium weighing 4.8 g.

Algorithm for solving the problem:
1) Drawing up an equation and placing coefficients.
2) Determination of the molar mass of magnesium.
3) Determination of the amount of magnesium substance.
4) Determination of the amount of magnesium sulfate substance according to the reaction equation.
5) Calculation of the molar mass of magnesium sulfate.
6) Calculation of the mass of magnesium sulfate.
Decision:
1) H2SO4 + Mg = MgSO4 + H2.
2) 24.
3) 4.8 / 24 = 0.2 mol.
4) According to the reaction equation, one mole of magnesium accounts for one mole of magnesium sulfate. This means that the amount of magnesium sulfate substance is 0.2 mol.
5) 24 + 32 + 64 = 120.
6) 120 * 0.2 = 24g – the answer.
