Answer:
4054 kcal of heat is released during complete combustion of 354 g of octane.

Heat of combustion of 1 mol of octane is kcal
Molar mass of octane = 114.23 g/mol
We know, no. of moles = (mass)/(molar mass)
So, kcal of heat is released during complete combustion of 114.23 g of octane.
So, amount of heat is released during complete combustion of 354 g of octane = kcal = 4054 kcal
Hence 4054 kcal of heat is released during complete combustion of 354 g of octane.
