The diameter of an oxygen molecule is 3. The ratio of molecular volume to the actual volume occupied by the oxygen gas at STP is

2 × 10 –4

1 × 10 –4

1.5 × 10 –4

4 × 10 –4

Text Solution

Verified by Experts

The correct answer is:

Here, diameter, d = 3Å

Molecular volume of oxygen gas,

N Avogadros number

Actual volume occupied by 1 mol of oxygen gas at STP

= 22,400

Therefore, ratio of the molecular volume in the actual volume of oxygen.
