The balance chemical equation is
2N2 + O2 ---> 2N2O.
We can solve how many moles of nitrous oxide gas from 1.65 moles of nitrogen gas. The balance equation is a critical information to answer this problem since it gives the ratio of nitrous oxide gas produced to the nitrogen used. 2 moles of nitrous oxide gas is produced from 2 moles of nitrogen gas is used. Hence there is 3.30 moles of nitrous oxide gas produced.
