There are four hydrocarbon and every substance has equal mass (such as 4.5kg). Which of the following substances will release the most energy when it is burned? (^H is proportional to the number of moles)

C12H26
C2H4
C8H16
C3H8

??? How do I even find this lol. At first i assume that since ^H is proportional to moles, that the answer would be C12H26...as you can see im completely chemistry retarded.
