`3.7 gm` of gas at `25^(@)C` occupied the same volume as `0.184 gm` of hydrogen at `17^(@)C ` and at the same pressure. What is the molecular mass of the gas ?

A

41.3 g

B

23.8 g

C

37.8 g

D

49.1 g

Text Solution

Verified by Experts

The correct Answer is:
A
Here we can use the equation `n_(1)T_(1)=n_(2)T_(2)` as pressure is same for both and their volume are equal. So,
`(3.7)/(M)xx298=(0.184)/(2)xx290.` This means that `M=41.32g//"mole"`
