The same amount of electricity was passed through two separate electrolytic cells containing solutions of nickel nitrate and chromium nitrate respectively. If 0.3 g of nickel was deposited in the first cell, the amount of chromium deposited is (At. wt. Ni= 59, Cr=52)

Options

A. 0.1g
B. 0.176g
C. 0.3g
D. 0.6g

Explanation

To solve the problem, we will use Faraday's second law of electrolysis, which states that the mass of a substance deposited during electrolysis is directly proportional to its equivalent weight and the amount of electricity passed through the cell.

### Step-by-Step Solution:

1. **Identify the Given Data**:
- Mass of nickel deposited (m_Ni) = 0.3 g
- Atomic weight of nickel (At. wt. Ni) = 59 g/mol
- Atomic weight of chromium (At. wt. Cr) = 52 g/mol
