Question

please solve q - 1.7 with full solution

Answer 1

hey mate .......just see that

Cu++ + SO4-- ---------> CuSO4

1 mole of copper gives 1 mole of copper sulphate....
moles of copper sulphate = 100/160 = 5/8 mole

so 5/8 mole of copper sulphate gives 5/8 mole of copper.....

so weight of copper = moles × atomic mass

so weight of copper = 5/8 × 64 = 40 gm...
