Under the same conditions, a gas diffuses `sqrt(2)` times as fast as `SO_(2)` gas. Find the molecular mass of the gas.

Text Solution

Verified by Experts

`(r_(gas))/(r_(SO_(2)))=sqrt((M_(SO_(2)))/(M_(gas)))=sqrt(2) or, (M_(SO_(2)))/(M_(gas))=2 or, M_(gas)=32g`
`therefore`Molecular mass of the gas=32.
