In Dumas' method for estimation of nitrogen $\displaystyle 1$ g of an organic compound gave $\displaystyle 150$ mL of nitrogen collected at $\displaystyle 300$ K temperature and $\displaystyle 900$ mm Hg pressure. The percentage composition of nitrogen in the compound is $\displaystyle \_\_\_\_$ % (nearest integer) (Aqueous tension at $\displaystyle 300 \mathrm{~K}=15 \mathrm{~mm} \mathrm{Hg}$ )
