A gas cylinder contains `12 xx 10^(24)` molecules of oxygen gas.
If Avogadro's number is `6 xx 10^(23)`. Calculate :
The volume of oxygen at S.T.P. present in the cylinder. [O = 16]

Explanation

To calculate the volume of oxygen gas at standard temperature and pressure (S.T.P.) present in the cylinder, we can follow these steps:

### Step 1: Calculate the number of moles of oxygen gas
The number of moles (n) can be calculated using the formula:
\[ n = \frac{\text{Number of molecules}}{\text{Avogadro's number}} \]

Given:
- Number of molecules of oxygen = \( 12 \times 10^{24} \)
