An ideal gas equation can be written as, P = ρ R T M 0 where ρ and M 0 are respectively,

An ideal gas equation can be written as, P=ρRTM0 where ρ and M0 are respectively,
  1. mass density, mass of the gas
  2. number density, molar mass
  3. mass density, molar mass
  4. number density, mass of the gas

Solution

Recall the ideal gas equation, in terms of pressure, volume and temperature, PV=nRTP=1V·mM0·RT, here R, is the universal gas constant, 

P=mVRTM0P=ρRTM0, the density is defined as mass per unit volume, ρ=mv,and, M0=the molar mass.
