What is the average speed of a molecule,...

What is the average speed of a molecule, having a molecular mass of `529.5 g mol^(-1)`. At temperature `100 K`

A

`1`

B

`2`

C

`3`

D

`4`

Text Solution

Verified by Experts

`u_(av)=sqrt((8RT)/(piM))`, `T=100 K`, `M=529.5 g mol^(-1)`
`=sqrt((8xx8.314xx100)/(3.14xx529.5))=2`
`:.` Average speed of molecule is `2` or (`b`)
