When potassium sulfate was dissolved in 270 grams of water, a solution with a mass fraction of 10%

When potassium sulfate was dissolved in 270 grams of water, a solution with a mass fraction of 10% was obtained. The mass of dissolved potassium sulfate is

In this solution, 270 grams of water will have a mass fraction of 90%.

Find the mass of the solution by dividing the mass of water by its mass fraction.

m solution = 270 / 0.9 = 300 grams;

Let us find the mass of salt by subtracting the mass of water from the mass of the solution.

m salt = 300 – 270 = 30 grams;

Check: 30 + 270 = 300;
