Chemistry - Mole Concept Question with Solution | TestHub

Number of moles of${\mathrm{O}}_2=\frac{1}{32}$
and number of mol of${\mathrm{N}}_2=\frac{4}{28}$
So$\frac{\text{Number}\text{of}\text{molecules}\text{of}{\text{O}}_{\text{2}}}{\text{Number}\text{of}\text{molecules}{\text{N}}_{\text{2}}}\text{=}\frac{\text{Number}\text{of}\text{mol}\text{of}{\text{O}}_{\text{2}}}{\text{Number}\text{of}\text{mol}\text{of}{\text{N}}_{\text{2}}}$
$=\frac{1/32}{4/28}=\frac{1}{32}\times \frac{28}{4}$
$=\frac{7}{32}=7:32$
