Given the following balanced reaction between nitrogen gas and oxygen gas to produce nitrous oxide gas, how many moles of nitrou
Artyom0805 [142]
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.

Hope This Helps!
