4C7H5N3O6 + 21O2 = 28CO2 + 10H2O + 6 N 2

According to the reaction equation, it can be seen that TNT and O2 have following stoichiometric ratio:

n (C7H5N3O6) : n (O2) = 4 : 21

n (O2) = 21/4 x n (C7H5N3O6) = 5.25 x n (C7H5N3O6)

n (C7H5N3O6) = m/M = 0.853/227 = 0.0038 mole

n (O2) = 5.25 x n (C7H5N3O6) = 5.25 x 0.0038 = 0.02 mole

m (O2) = n x M = 0.02 x 32 = 0.64 g = 640mg
