If the `v_(rms)` is `30R^(1//2)` at `27^(@)C` then calculate the molar mass of gas in kilogram.

A

1

B

2

C

4

D

`0.001`

Text Solution

Verified by Experts

The correct Answer is:
D
`v_(rms)=sqrt((3RT)/(M))`
`sqrt(30^(2)R)=sqrt((3RT)/(M))implies 30xx30R=(3Rxx300)/(M)`
`implies M=(3xx300)/(30xx30) 1g= 0.001 kg`
