  1. number of molecules
  2. average potential energy
  3. ratio of specific heats
  4. density

A
number of molecules
B
average potential energy
C
ratio of specific heats
D
density
Solution
Verified by Toppr

We know, R=PVnT
assuming P,V and T to be constant.
Also we know, that equal volume of gases contain equal number of molecules, hence the value of R is also constant.
