Answer:

The mass of sodium sulphate required to prepare its 20% solution in 100g of water is 25 g

Explanation:

percentage of solution = 20 %

mass of water = 100 g

mass of sodium sulphate = ??

let us suppose the mass of sodium sulphate is "x"

the mass of solution will be = (x + 100g)

to find the x g of solute in x + 100g of solution

20 % = (x / x + 100g ) 100

by solving we get

20x + 2000 = 100x

2000 = 80x

x = 25 g

The mass of sodium sulphate required to prepare its 20% solution in 100g of water is 25 g
