When 235U fissions, the fission products are not always the same and exactly two

Question

When 235U fissions, the fission products are not always the same and exactly two neutrons are not always released. An example of one fission reaction is

a) What is the energy released in this fission?
Q = MeV *
180.76 OK I GOT THIS ANSWER

b) Another example of possible results is

Q = MeV *
173.29 OK I ALREADY GOT THIS ANSWER

c) Lets assume that these are the only two fission reactions that take place (they are not), and that they take place at equal rates so the amount of energy released in every fission of 235U is the average of these two. How many gallons of gas would have to be burned to release the same amount of energy released when one kilogram of 235U undergoes fission? (A gallon of gasoline releases about 2.0X108J of energy when burned.)
Ngallons = gallons

Explanation / Answer

?BE = BEproducts – BEreactamts ?BE = BEproducts – BEreactamts ?BE = (BESr-88 + BEXe-136 ) – (BEU-235) ?BE = (BESr-88 + BEXe-136 ) – (BEU-235) ?BE = (783.2MeV + 1156MeV ) – (1786 MeV) = 153.2 MeV
