The respective speeds of five molecules ...

The respective speeds of five molecules are 2,1.5,1.6,1.6 and 1.2 km/sec. The most probable speed in km/sec will be

A

`2`

B

`1.58`

C

`1.6`

D

`1.31`

Text Solution

Verified by Experts

The correct Answer is:
C

Since maximum number of molecules travel with speed `1.6 km//s` so `v_("mp") = 1.6 km//s`
