Calculate the average kinetic energy (in joule) per molecule in `8.0 g` of methane at `27^(@)C`.

A

`6.21 xx10^(-20) J// "molecule"`

B

`6.21 xx10^(-21) J// "molecule"`

C

`6.21 xx10^(-22) J// "molecule"`

D

`3.1 xx10^(-22) J// "molecule"`

Text Solution

Verified by Experts

The correct Answer is:
B
Average `KE=(3)/(2)xx(8.314)/(6.023xx10)^(23)`
`6.21xx10^(-21)J//"molecule"`
