two cylinder a and b contains the same gas at same temperature, the pressure and the volume of A are both twice thrice of B.then the ratio of the no of molecules of A and ​

Answer 1

Answer: PV=nRT

∴n  

B

​  

=  

RT

PV

​  

 and n  

A

​  

=  

R×2T

2P×2V

​  

 

or n  

A

​  

=  

RT

2PV
