Question

how much copper obtained from 100 g of copper sulphate​

Answer 1

Answer:

1 mole of CuSO4 contains 1 mole of copper. 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.

Answer 2

Here's your answer ✨

Explanation:

Gram molecular mass of CuSO4 = 64+32+16×4

= 160g

Mass of CuSO4 given= 100 g

Mole of CuSo4= 100/160= 0.625 mole

One mole of CuSO4 contains :

One mole of Cu 2+ and

One mole of SO4 2-

So 0.625 mole of CuSO4 contains 0.625 moles of Cu 2+ and 0.625 moles of SO4 2-.

Thus Cu2+=0.625 ×64= 40 g
