    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 ...

    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.
