ch4aika [34]

Answer:

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

Explanation:

Heat of combustion of 1 mol of octane is 1.308\times 10^{3} kcal

Molar mass of octane = 114.23 g/mol

We know, no. of moles = (mass)/(molar mass)

So, 1.308\times 10^{3} 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 = (\frac{1.308\times 10^{3}}{114.23})\times 354  kcal = 4054 kcal

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