Assuming that air at STP contained 80% by volume of nitrogen, the volumeof air at STP that contains `4.8xx10^(23)` molecules of notrogen is

A

18 L

B

44.8 L

C

22.4 L

D

11.2 L

Text Solution

Verified by Experts

The correct Answer is:
C
22.4 litres air - STP - `6.023xx10^(23)` molecules
`therefore` Nitrogen molecules `=(80)/(100)xx6.023xx10^(23)`
`~~4.8xx10^(23)` molecules
