Calculate the average volume available to a molecule in a sample of oxygen gas at S.T.P. Also calculate the average distance between neighbouring molecules if a oxygen molecule is assumed to be spherical.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the volume occupied by 1 mole of oxygen gas at STP
At Standard Temperature and Pressure (STP), the volume occupied by 1 mole of any gas is 22.4 liters. We can convert this to cubic centimeters (cm³):
\[ 1 \text{ liter} = 1000 \text{ cm}^3 \]
Thus,
...
