Question

how much copper sulphate will require saturating 80 grams of water at 20 degree celcious .if solubility of copper sulphate at 20degree celcious is 25?

MathMate
Solubility is defined as the number of grams of solute that will saturate 100 grams of solvent at a given temperature.

So at 20 degrees, we know that the solubility of CuSO4 is 25.

Mass of water (solvent)=80 g
Use ratios:

25:100 = x:80
Solve for x to get x=25*80/100=20g
