Answer #1

2CH3NO2(l)+3/2O2(g)→2CO2(g)+3H2O(l)+N2(g) ΔHrxn = -1418 kJ

according to the reaction

122 grmas of nitromethane on produces --------------------------------------------1418kj of energy

7.68*10^3 grams of nitromethane gives ----------------------------------------------------?

                = 7.68*10^3*1418/122

                = 89264.26kj of energy is released
