Question 10

At high temperature, nitrogen and oxygen form nitrogen monoxide according to the equation:

$N2+O2→2NO\text{N}_2 + \text{O}_2 \rightarrow 2\text{NO}$

The nitrogen monoxide formed has a volume of 9.6 dm³ at room temperature and pressure. One mole of any gas occupies 24 dm³ at room temperature and pressure. The relative formula mass of nitrogen, $N2\text{N}_2$ , is 28.

What is the mass of nitrogen that reacted?
