If 224 mL of triatomic gas has a mass of 1 g at 273 K and 1 atm. Pressure, then the mass of one atom is

A

`8.30xx10^(-23) g`

B

`2.08xx10^(-23)g`

C

`5.53xx10^(-23)g`

D

`6.24xx10^(-23)g`

Text Solution

Verified by Experts

The correct Answer is:
C
`PV=(w)/(m)RT`,
`:. 1xx(224)/(1000)=(1)/(m)xx0.0821xx273`
`:. m=100`
`:' 3 N` atoms of gas weighs `=(100)/(3xx6.023xx10^(23))`
`=5.53xx10^(-23)g`
