How much copper can be obtained from 100 g of copper sulphate (CuSO4)?
Given:
Mass of Copper Sulphate = 100g
Atomic Mass of Copper = 63.5g
Atomic Mass of Sulphur = 32g
Atomic Mass of Oxygen = 16g
Molecular Mass of CuSO4 = 63.5 + 32 + [4×16]
= 159.5g
63.5g of Copper [Cu] → 159.5g of Copper Sulphate
X g of Copper [Cu] → 100 g of Copper Sulphate
X = [100×63.5]/159.5
= 6350/159.5
= 39.812
≈39.81g
Therefore 39.81g of copper can be obtained from 100g of copper sulphate.
