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.

Aspirin can be prepared from salicylic acid (C7H6O3), which has a molar mass of 138.12 g/mol, and acetic anhydride (C4H6O3), which has a molar mass of 102.04 g/mol. The density of acetic anhydride is 1.082 g/mL. C7H6O3+C4H6O3⟶C9H8O4+C2H4O2 What is the yield, in grams, of aspirin (C9H8O4), which has a molar mass of 180.15 g/mol, possible when reacting 2.18 g of salicylic acid with 1.05 mL of acetic anhydride?
