OK, now more on this problem.
1. we will assume that 1 ton reacted. 1 ton = 2240 lb x 454g =1016960g
2. 1 mol of NH4NO3 is 80 g, so 1016960 g is 12712 mol
3. According to this equation 52 NH4NO3 + C17H36 = 52 N2 + 17 CO2 + 122 H2O
52 mol of NH4NO3 produces 52+17+122=191 moles, then 12712 mol produces 46692 mol
4. 1 mol = 22.4L, so 46692 mol = 1045900 L = 1.04 x 10^6
Please advise if this makes sense.
Thank you
