Answer:
6.46 x 10^4 kJ
Explanation:
Calculate moles of CH3NO2:
kg to g:
5.56 kg x 1000 = 5560 g
molar mass of CH3NO2:
12.01 + 3.024 + 14.01 + 32.00 = 61.04 g
moles= mass / molar mass
moles = 5560 g / 61.04 g/ mol
moles = 91.1
Then calculate total heat
Total heat = (delta H / 2 mol) x moles of CH3NO2
Plug into calculator just like this
Total heat = (-1418/2) x 91.1
Total heat = 64589.9 kJ
move the decimal over 4 places:
6.46 x 10^4 kJ is the result
