The overall balanced chemical reaction for this is:

Detonation of Nirtoglycerin

4 C3H5N3O9 - - > 12 CO2 + 6 N2 + O2 + 10 H2O

Therefore:

2.00 mL x 1.592 g/mL = 3.184 g

3.184 g / 227.1 / mol = 0.0140 mol nitroglycerin

4 moles - - > 12 + 6 + 1 + 10 = 29 moles of gas

0.0140 mol x (29/4) = 0.1017 moles of gases or (0.102 mol)
