Three electrolytic cell `A,B`, and `C` contaning solutions of `ZnSO_(4), AgNO_(3)`, and `CuSO_(4)`, respectively, are connected in series. A steady current of `1.5A` was passed through them until `1.45 g` of silver deposited at the cathode of cell `B`. How long did the current flow ? What mass of copper and zinc were deposited ?

Explanation

To solve the problem step by step, we will follow these main points:

1. **Calculate the charge required to deposit 1.45 g of silver.**
2. **Determine the time for which the current flowed using the charge and current.**
3. **Calculate the mass of copper deposited using the charge.**
4. **Calculate the mass of zinc deposited using the charge.**

### Step 1: Calculate the charge required to deposit 1.45 g of silver.
