Explanation:
100 g of dilute solution of CuSO
4
contain
=1.2×10=12.0gCuSO
4
Mass of water present in dilute solution
=(100−12)=88g
To saturate 100 g of water, CuSO
4
required = 25 g
So, to saturate 88 g of water, CuSO
4
required =
100
25
×88=22g
Thus, the mass of CuSO
4
to be added to 100 g of dilute solution to saturate it =(22−12)=10g.
