Based on the mole ratio of the reaction, 30 moles of NO2 will be produced from 15 moles of oxygen.
<h3>What is mole ratio of a reaction?</h3>
The mole ratio of a reaction is the ratio in which moles of reactants combine with themselves to form moles of products.
The equation of the reaction is given below:

The mole ratio of NO2 to oxygen is 2 : 1
Molles of NO2 produced from 15 moles of O2 = 15 × 2 = 30 moles
Therefore, 30 moles of NO2 will be produced from 15 moles of oxygen.
