Question

How much copper can be obtained from 100gram of copper sulphate.​

Answer 1

Answer:

1 mole of CuSO4 contains 1 mole of copper.

Molar mass of CuSO4

= Atomic mass of [Cu × 1 + S × 1 + O × 4 ]

=(63.5) + (32.00) + 4(16.0) = 63.5 + 32.0 + 64.0

= 159.5 g

Here molar mass of Cu is 159.5 g so that 159.5 of CuSO4 will produce 1 mole of Cu and mass of 1 mole of Cu is 63.5 g of copper.

So 100 g of CuSO4 will produce = \[\frac{{63.5 \times 100}}{{159.5}} = 39.8g\]

Explanation:

Amount of copper obtained from 100 g CuSO4 = 39.8 g
