The size distribution of dark clouds and of H II regions were used to derive a distance of 440±22 kpc for M31. Some galactic H II regions and dark clouds were combined with the same ingredients in M31 to study the mass spectrum of both phenomena. A gas to dust ratio of 1000:1 has been derived for M31. Radii of the classical H II regions as derived in this work using distance of 440 kpc agree with the galactic classical H II region radii.
