Question

Calculate the mass of potassium sulphate required to prepare its 10% solution in hundred gram water

Answer 1

11.15 g of potassium sulphate required to make 10% in 100 g water

Answer 2

let the solvent be X

then the solution = X+100g

formula = mass of solution/mass of solution ×100

X/X+100 ×100 = 10%

X/X+100 = 10/100

X/X+100 = 1/10

10x = X+100 (cross multiplication)

10x-x = 100

9x = 100

X=100/9

X=11.1
