Question

Calculate the mass of potassium sulphate required to prepare its 10% solution in 100g of water.

Answer 1

Mass of solution = 100g

percentage = 10

mass of solute (potassium sulphate) = ??

We know that,

mass by mass percentage =

mass of solute/mass of solution × 100

here,

mass of potassium sulphate/100g × 100 = 10%

=> on solving,

mass of potassium sulphate = 10g


Hope it helps dear friend ☺️
