The average distance between molecules of an ideal gas at STP is approximately of the order of

A

1 nm

B

100 nm

C

100 cm

D

1m

Text Solution

Verified by Experts

The correct Answer is:
A

`n=(PV)/(RT)=(10^5 xx 1)/((25)/(3)xx300)=40 implies N = 40 xx 6.023 xx 10^(23)=24 xx 10^(24)`
Average distance = `(1/N)^(1//3)=1nm`
