| MgSO4 – magnesium sulfate.

1) Find the molar mass of magnesium sulfate according to the periodic table: 24 + 32 + 4 * 16 = 120.

2) Find the mass of the solute sulfate in its solution. To do this, we multiply the amount of magnesium sulfate substance by its molar mass: 0.2 * 120 = 24g.

3) Calculate the mass of the solution. To do this, we multiply the mass of the solute by one hundred percent and divide by the mass fraction of the substance: 24 * 100/16 = 150g.

Answer: the mass of the magnesium sulfate solution is 150 g.
