Question

How much of cu can be obtained from 100g cuso4

Answer 1

Answer:

40g

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
