Molecular weight of$\mathrm{\text{c}}\mathrm{\text{o}}\mathrm{\text{m}}\mathrm{\text{p}}\mathrm{\text{o}}\mathrm{\text{u}}\mathrm{\text{n}}\mathrm{\text{d}}=108$

${\text{C}}^{12}\to 12\times 6=72$

${\text{H}}^1\to 1\times 8=8$

${\text{N}}^{14}\to 14\times 2=28$

Total molecular weight$=108$

$\therefore$Molecular formula$={\text{C}}_6{\text{H}}_8{\text{N}}_2$

atom ratio$\frac{72}{8}:\frac{8}{8}:\frac{28}{8}$

$=9:1:3.5$
