Two balloons are filled, one with pure He gas and the other by air, respectively. I f the pressure and temperature of these balloons are same, then the number of molecules per unit volume is
Text Solution
Verified by ExpertsThe correct answer is:
B
I deal gas equation can be written as
pv = nRT
or 
= 
= constant
So, at constant pressure and temperature, all gases, will contain equal number of molecules per unit volume.
