Elemental analysis of an organic compound gives the following elemental mass percentages: \( \mathrm{H}, 6.478 \% ; \mathrm{C}, 60.52 \% ; \mathrm{N}, 25.67 \% \) and \( 0,7.330 \% \). Vapourization of \( 241 \mathrm{mg} \) of the compound in a \( 75-\mathrm{mL} \) bulb at \( 160^{\circ} \mathrm{C} \) gives a pressure of \( 0.523 \) bar. What is the molecular formula of the compound? \( \begin{array}{lll}\text { C } & \mathrm{H} & \mathrm{N}\end{array} \)
