Answer: Energy released during the reaction is 0,299 kcal
Explanation: ΔH is the amount of energy released when 1 mol of C3H8 reacts, but there is no 1 mol but less, 3.40 x 10^20 molecules
Using Avogadro's number is possible to calculate the number of moles
The product of the mol number and ΔH is the energy released during the reaction
It tells us two expressions that mean the same thing/something that can represent the same thing.
