Solution Summary

The solution gives a step by step answer to finding the mass of NaNO2 required to produce a certain amount of N2 under given conditions in a clear manner with explanation throughout.

Solution Preview

First you need a chemical reaction producing N_2 gas.

2 NaNO_2 --> 2Na + N_2 + 2 O_2

use the ideal gas law to figure out how many moles of N_2 gas that is.

n = PV/RT

V = 40 mL = 0.040 ...
