Question

A lab mate of the student asked her for some solid $CuCl_{2}$ . While she was lifting the bottle from a shelf, the lid of the bottle slipped and some amount of $CuCl_{2}$ fell in the $CuSO_{4}$ compartment at constant volume. She measured the emf of the cell again and found that it had increased by 9 mV . She used this calculate the mass of $CuCl_{2}$ in grams that had split into the Daniel cell.

(Molecular mass of $CuCl_{2}$ = 135 g)
