Calculate the work of expansion when 100g of water is electrolysed at a constant pressureof1 atm and temperature of `25^(@)C`.

Explanation

To calculate the work of expansion when 100 g of water is electrolyzed at a constant pressure of 1 atm and a temperature of 25°C, we can follow these steps:

### Step 1: Write the Electrolysis Reaction
The electrolysis of water can be represented by the following reaction:
\[ 2 \text{H}_2\text{O} \rightarrow 2 \text{H}_2 + \text{O}_2 \]

### Step 2: Calculate Moles of Water
First, we need to calculate the number of moles of water in 100 g. The molar mass of water (H₂O) is approximately 18 g/mol.
