The perfect gas equation can be written as pV=μRT where,μ=numberofmoles andR=NAkB=universalconstant...(ii) Here,μ=M0m=NAN
where, m= mass of gas, M0= molar mass, N= number of molecules
and NA= Avogadro's number.
Using, Eqs. (i), (ii) and (iii), we get pV=kBNT or p=kBnT
where, n= number density =VN
Also, p=M0ρRT [∵V=ρM0]
where, ρ= density.
Hence, all given options are correct.
