A researcher studying the nutritional value of a new candy places a 3.40 gram sample of the candy inside a bomb calorimeter and combusts it in excess oxygen. The observed temperature increase is 2.36 C. If the heat capacity of the calorimeter is 46.80 kJ*K-1, how many nutritional calories are there per gram of the candy?
See the answers to your other questions and
Remember the equation
ΔH = -Ccal x ΔT.
1) make sure ΔT in in K
2) 1 nutritional calorie = 4.2 kJ
3) give the answer on a per gram basis of candy
I think you can take it from here!!
