2 moles of H atoms at NTP occupy a volume of:

Options

A. 11.2 litres
B. 44.8 litres
C. 2 litres
D. 22.4 litres

Answer

To find the volume occupied by 2 moles of hydrogen atoms (H) at Normal Temperature and Pressure (NTP), we can follow these steps:

### Step 1: Understand the Concept of Moles
1 mole of any gas at NTP occupies a volume of 22.4 liters.

### Step 2: Identify the Substance
We are dealing with hydrogen atoms (H). However, hydrogen gas (H2) is typically what we refer to in gas calculations. Since 1 mole of H2 contains 2 moles of H atoms, we need to convert moles of H atoms to moles of H2 gas.

### Step 3: Calculate Moles of H2 from H Atoms
Given that we have 2 moles of H atoms:
- 2 moles of H atoms = 1 mole of H2 gas (since 1 mole of H2 contains 2 moles of H atoms).

### Step 4: Calculate the Volume Occupied by H2
Now, we can use the volume occupied by 1 mole of H2 gas at NTP:
- 1 mole of H2 gas occupies 22.4 liters.

### Step 5: Conclude the Volume for 2 Moles of H Atoms
Since 2 moles of H atoms correspond to 1 mole of H2 gas:
- Volume occupied by 1 mole of H2 = 22.4 liters.

Thus, the volume occupied by 2 moles of H atoms at NTP is **22.4 liters**.

### Final Answer:
**22.4 liters**
