<span>Molar Mass
Gas A 53.8% Nitrogen
462% Carbon
53.8 N/14 = 3.84
46.2 C/12 = 3.85
So since these are identical, and there is no hydrogen (which eradicates HCN as a possibility) we are going to cut to the chase and say since its empirical formula must be CN, the molecular formula is (CN)2, or Cyanogen.
So it gives MW = 52</span>
