Average volume available to a molecule in sample of a gas at STP is

A

`1.66xx10^(-24)cm^(3)`

B

`3.769xx10^(-20)cm^(3)`

C

`22400 cm^(3)`

D

unpredictable

Text Solution

Verified by Experts

The correct Answer is:
B
Volume occupied by 1 mole of a gas at STP
`=22400" cm"^(3)`
No. of molecules present in 1 mole of the gas
`=6.02xx10^(23)`
`:.` Volume available per molecule `=(22400)/(6.02xx10^(23))`
`=3.72xx10^(-20)cm^(3)`
