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
