Calculate how long it will take to deposit 1.0 g of chromium when a current of 1.25 . A flows through a solution of chromium (III) sulphate . (Molar mass of Cr = 52).

Explanation

To solve the problem of calculating how long it will take to deposit 1.0 g of chromium when a current of 1.25 A flows through a solution of chromium (III) sulfate, we can follow these steps:

### Step 1: Identify the relevant formula
The mass deposited during electrolysis can be calculated using the formula:
\[ W = Z \cdot I \cdot t \]
where:
- \( W \) = mass deposited (in grams)
- \( Z \) = electrochemical equivalent (in grams per coulomb)
