What is the RMS speed of a moist particle of mass `10^(-12)` g at 27°C according to kinetic molecular theory?

A

0.35 cm/sec

B

0.45 cm/sec

C

0.6 cm/sec

D

0.7 cm/sec

Text Solution

Verified by Experts

`C = sqrt((3RT)/(M)) = sqrt((3 xx 8.314 xx 10^(7) xx 300)/(10^(-12) xx 6 xx 10^(23)))`
`= 0.35 cm//gm`.
