Answer:

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.......

Answer:

1 mole of CuSO4 contains 1 mole of copper.

Molar mass of CuSO4 = (63.5) + (32.00) + 4(16.00)

= 63.5 + 32.00 + 64.00 = 159.5 g

159.5 g of CuSO4 contains 63.5 g of copper.

∴ copper can be obtained from 100 g of copper sulphate = (63.5/159.5)×100 = 39.81g
