Question

How much copper can be obtained from 100 g of cuso4?

Answer 1

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

Answer 2

Answer:

39.81g of cu

Explanation:

1 mol of CuSO4 contains 1 mol of Cu

molar mass of CuSO4  = 63.5 + 32 + 64 = 159.5

∴159.5 g of CuSO4 contains 63.5 g of Cu

so 100 g of CuSO4 contains how much amount of Cu

amount of Cu in 100 g of Cu$ = 63.5/159.5X 100 = 39.81 g
