Question

A toxic gas. a, consists of 53.8% nitrogen and 46.2% carbon by mass. at 273 k and 1.01 x 10^5 pa, 1.048g of a occupies 462 cm^3. determine the empirical formula of
a. calculate the moral mass of the compound and determine its molar mass

Answer 1

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
