Basically in part (a) you had to compute the molar mass of 
nitroglycerine (using the provided periodic table) and divide the mass 
by the molar mass to find the number of moles of nitroglycerine.  The 
molar mass on nitroglycerine is 227 grams/mol.

908/227 = 4 moles of nitoglycerine.

Now -- if you look at the chemical equation, 4 moles of nitroglycerine 
makes 12 moles of CO2, 10 moles of H2O, 6 moles of N2 and1 mole of O2.  
Adding up the moles of gas you get 29 moles.

Use that number in the idea gas law for part (b)

The mass with the smallest molar mass (water) will be moving the fastest.

  You might see something like this on the final...
