Nitroglycerine is a shock-sensitive compound that decomposes as follows:  2 C3H5N3O9(l)     -->     6 CO2(g)   +  3  N2(g)   +   ½ O2(g)   +   5 H2O(g) 10.0 kg of nitroglycerine sits in a 5.0-L cylinder.  A chemist, angry that an experiment didn’t work, foolishly kicks the cylinder, thereby inadvertently performing his last and most dramatic experiment.  The final temperature of the product mixture is 595 oC.  Assume ideal gas behavior and complete decomposition.  Calculate the total pressure (atm) in the cylinder the moment before the explosion.
