Mass of the solution = mass of solute + mass of solvent
Given that the mass percent of sodium sulphate solution is 20%.
Let the mass of sodium sulphate which is required to prepare this solution be x grams.
Given that the mass of water is 100 g.
20 = [x/(x + 100)] * 100
20/100 = [x/x + 100]
1/5 = x/x + 100
x + 100/5 = x
x + 100 = 5x
5x - x = 100
4x = 100
x = 100/4
x = 25
Thus, 25g of sodium sulphate is required.

if u find it useful please mark as best
sodium sulphate does not dissolve that much 25g in 100 g of water.. does it dissolve to become a solution?
yes, sir this is the answer iam 100% sure
i am not talking about calculations. Does 25gms of sodium sulphate dissolve in 100gm or 100ml of water. If it does not dissolve, then it does not form solution. right?
yeahh. if it doesnt disolve,it wont form a solution
