A gaseous mix...

Question

A gaseous mixture of $N_{2}$ and $O_{2}$ containing $60 %$ by mole $N_{2}$ is allowed to react with each other according to the following equation.
$N_{2} + O_{2} \to N O_{2}$
If $92$ g of $N O_{2}$ is formed, find the mole of $N_{2}$ present in the mixture.

Solution

Suppose the number of moles present in mixture is $x$ .
$\frac{1}{2} N_{2} 0.6 x + O_{2} 0.4 x \to N O_{2} 0.4 x$
The molar mass of $N O_{2}$ is $46$ g/mol. $92$ g of $N O_{2}$ is obtained.
$0.4 x \times 46 = 92$
$x = \frac{2}{0.4}$
So, $0.6 x = \frac{2}{0.4} \times 0.6 = 3$ .
Hence, the mole of $N_{2}$ present in the mixture is $3$ .
