peanut burning?

1 ⤊

in an experiment we burned peanuts to find out the energy content of it. The formula we used was (4.18*mass of water*change in temperature) / amount of food burnt. using that equation i get 11067 joules per gram or j/g. in kilojoules per gram i get 11.067. does this sound like reasonable values for a peanut? and is the formula ok?

100 gms of peanuts produce 2450 kJ or 24.50 kj/gm

I'm not sure where you got the 4.18 from.

In answer to the previous answer: 1 calorie = 4.18 joules

1 calorie = the amount of energy required to raise the temperature of 1 gram of water by 1 degree celsius.
