Chapter 10, Problem 77RQ

The explosive PETN, pentaerythritol tetranitrate, is one of the most powerful explosives known. It reacts with the following balanced equation

$\begin{array}{l}\text{C}{\left({\text{CH}}_{\text{2}}{\text{ONO}}_{\text{2}}\right)}_{\text{4}}\left(s\right)\stackrel{}{\to }\text{2CO}\left(g\right){\text{+ 4H}}_{\text{2}}\text{O}\left(g\right)\hfill \\ {\text{+ 3CO}}_{\text{2}}\left(g\right){\text{ +2N}}_{\text{2}}\left(g\right)\hfill \end{array}$

How many grams of PETN will react to fill a 30.0 L sphere to a pressure of 720 torr at a temperature of $\text{25 °C}$?
