Solution :
For 100 g of Copper Sulphate, 25.45 g is Copper. Therefore For 40 g of Copper Sulphate how much Copper is required ?
This can be solved by Ratio Method.
So, 100 g : 25.45 g : 40 g : ?
So 100 * x = 25.45 * 40
=> x = 25.45 * 40 / 100
=> x = 10.18 g
Therefore 40 g of Copper Sulphate will contain 10.18 g of Copper.
Hope it helped !
