When 100.0g of gas undergoes combustion,9560 kJ of energy are released.how much heat is relased (4.184J=1cal)?

Question

I need to know the steps to figure this out. I can't find anything close in my textbook to plug the figures in. I don't even need the actual answer if someone can show me how to set up the equation. Thanks!

Answer 1

the 9560 kJ is the amount of heat (energy)

we can change it to kilocals:

9560 kJ @ 1 Kcal/ 4.184 kJ = 2285 kilocalories

& we can divide eithe by 100.0 grams to get the heat released per gram
