`1 gH_(2)` gas `STP` is expanded so that the volume is doubled. Hence, work done is

Options

A. `22.4 L-atm`
B. `5.6 L-atm`
C. `11.2 L-atm`
D. `44.8 L-atm`

Explanation

To solve the problem of calculating the work done when 1 g of H₂ gas is expanded at STP (Standard Temperature and Pressure) so that its volume is doubled, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Conditions at STP**:
- Standard Temperature (T) = 273 K
- Standard Pressure (P) = 1 atm
- Volume of 1 mole of gas at STP = 22.4 L
