Chemistry Problems Solved! Nitroglycerine explodes violently to form several gasses, according to

Nitroglycerine explodes violently to form several gasses according to the following equation:
4 C3H5O9N3 --= 12 CO2(g) + O2(g) + 6N2(g) + 10 H2Og
A sealed 1.00 mL container filled with 2.8 g of nitroglycerine is detonated. If the Temperature inside the container is 300˚C and assuming that the container would not break upon detonation, what is the pressure inside the container right after detonation? (Put your answer in atm's)
