Hydrogen gas obtained by electrolysis of `18g` of water is heated to `127^(@)C` at a pressure of `2 atm`. Calculate the volume it would occupy.

Explanation

To solve the problem of calculating the volume of hydrogen gas obtained from the electrolysis of 18g of water when heated to 127°C at a pressure of 2 atm, we will follow these steps:

### Step 1: Determine the amount of hydrogen gas produced
1. **Electrolysis of Water**: The balanced equation for the electrolysis of water is:
\[ 2H_2O \rightarrow 2H_2 + O_2 \]
From this equation, we see that 1 mole of water produces 1 mole of hydrogen gas.
