1.	At 0^(@)C, the density of a gaseous oxide at 2 bar is same as that of nitrogen at 5 bar. What is the molecular mass of the oxide ?
Answer» Solution :Using the expression, `d=(MP)/(RT)`, at the same temperature and for same DENSITY, `underset(("GASEOUS oxide"))M_(1)P_(1) ""= "" underset((N_(2))M_(2)P_(2)` (as R is constant) `:."" M_(1)xx2=28xx5 ("Molecular mass of "N_(2)=28 U)` or `"" M_(1)=70 u`
