If air contains

{\mathrm{N}_2}

and

{\mathrm{O}_2}

in volume ratio

4:1

. The average vapour density of air is:

View answer and explanation

Correct option: C

14.4

Option C (14.4) is correct because the average vapor density is calculated from the average molecular weight of the air mixture, considering the volume ratio of nitrogen and oxygen.
