PART 2. Answer all questions and show all work. Partial credit will be given. When nitroglycerin (C3Hs(NOs)s ) explodes, a huge volume of gas is produced causing the shockwave associated with an explosion. The reaction is as follows 4 CsH5(NO3)3(1) 6 (g) + O2(g) + 12 CO2(g) + 10 H2O(g) During a construction accident, 500 mL of nitroglycerin was dropped and subsequently exploded. (density of nitroglycerin-1.60 gmL) (12 pts) How many grams of nitroglycerin were dropped? . Determine the volume ( in liters) of CO2(g) released, at STP, when 500 mL of nitroglycerin exploded. 2371

Explanation / Answer

a)

mass of NitroGlycerin -->

mass = Density * Volume = 1.6*500 = 800 g of NG.

b)

volume of CO2 released given this

MW of Ng = 227.0865

mol of NG = mass/MW = 800/227.0865 = 3.522

ratio is:

4 mol of NG = 12 mol of CO2

mol of CO2 = 3*3.522t = 10.566 mol of CO2

1 mol of CO2 = 22.4 L

10.566 mol -_> 10.566*22.4 = 236.678 Liters of CO2
