Given the following balanced reaction between nitrogen gas and oxygen gas to produce nitrous oxide gas, how many moles of nitrous oxide gas are produced from 1.65 moles of nitrogen gas?

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 1.65 moles of nitrous oxide gas produced.
