Question

Density of a gas is related to molar mass by:

  1. A
    d=PMRTd=\frac{PM}{RT}
    Correct
  2. B
    d=RTPMd=\frac{RT}{PM}
  3. C
    d=PMRTd=\frac{P}{MRT}
  4. D
    d=PMRTd=PMRT

Correct answer

d=PMRTd=\frac{PM}{RT}

Explanation

From PV=nRTPV=nRT and n=m/Mn=m/M, density becomes m/V=PM/RTm/V = PM/RT.
