From the given chemical equation we see that 43 kcal of
energy is needed for every 2 moles of NO. First let us calculate the moles of
NO with a molar mass of 30 g/mol.
moles NO = 112 g / (30 g/mol) = 3.73 mol
So the total heat absorbed is:
heat = (43 kcal / 2 mol) * 3.73 mol
<span>heat = 80.195 kcal</span>
