A gas cylinder can hold 1 kg of hydrogen gas at room temperature and 1 atm pressure. Calculate the following:
The mass of carbon dioxide which the cylinder could hold under similar conditions of temperature and pressure. (Molar mass of CO2 = 44 g)

Explanation

To solve the problem, we need to calculate the mass of carbon dioxide (CO2) that can be held in the gas cylinder under the same conditions of temperature and pressure as 1 kg of hydrogen gas (H2).

### Step-by-Step Solution:

1. **Identify the Given Information:**
- Mass of hydrogen gas (H2) = 1 kg = 1000 g
- Molar mass of hydrogen (H2) = 2 g/mol
- Molar mass of carbon dioxide (CO2) = 44 g/mol
