Chapter 7, Problem 7.120CP

As we learned in Chapter 5, an automobile airbag inflates when ${\text{NaN}}_{\text{3}}$ is converted to $\text{Na}$ and ${\text{N}}_{\text{2}}$ according to the equation, ${\text{2 NaN}}_{\text{3}}\to {\text{ 2 Na + 3 N}}_{\text{2}}\text{.}$ What volume of ${\text{N}}_{\text{2}}$ would be produced if 100. g of ${\text{NaN}}_{\text{3}}$ completely reacted at STP?
