The mean free path of nitrogen molecules at a pressure of 
and temperature 
is 
. If the number density of molecules is 
, then the molecular diameter is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
We have the mean free path as 
and the number of molecules per unit volume (or number density) as 
Substituting these values in the expression of mean free path 
, we get the molecular diameter as follows:
