An ideal gas equation can be written as
P=ρRTM0where ρ and M0are respectively,
Number density, mass of the gas
Mass density,mass of the gas
Number density, molar mass
Mass density, molar mass
Perfect gas equation can be written as
PV=μRTPV=MM0RTP=MVRTM0P=ρRTM0
where ρis mass density and M0 is molar mass.
