A mixture contains 72 cm3 of nitrogen monoxide and 50 cm3 of oxygen. The gases react according to the equation
2NO(g)+O2(g)→2NO2(g)\mathrm{2NO(g) + O_2(g) \rightarrow 2NO_2(g)}2NO(g)+O2(g)→2NO2(g)
The reaction continues until one reactant is completely used. All gas volumes are measured at the same temperature and pressure.
Calculate the total volume of gas present after the reaction.
