How many grams of salt and water are in 600g of 20% sodium sulfate solution?

Mass of solution = 600 g.

Mass fraction of dissolved substances = 20% = 0.2.

The mass of the dissolved substance = 0.2 * 600 = 120 g.

Mass of water = 600 g – 120 g = 480 g.

Answer: the mass of sodium sulfate is 120 g, the mass of water is 480 g.
