The number of molecules in 8.96L of a gas at `0^(@)C` and 1 atmosphere pressure is approximately

A

`6.02xx10^(23)`

B

`12.04xx10^(23)`

C

`18.06xx10^(23)`

D

`24.08xx10^(22)`

Text Solution

Verified by Experts

The correct Answer is:
D
`:'` 22.4 L of a gas t STP has no. of molecules `=6.023xx10^(23)`
`:.` 8.96 L of a gas at STP has no. of molecules `=(6.02xx10^(23)xx8.96)/22.4=2.408xx10^(23)=24.08xx10^(22)`.
