While a 0.579g sample of a mixture of volatile hydrocarbons is burned in a bomb calorimeter with a heat capacity of 3389 J/degrees Celsius, the temperature rises by 6.40 degrees Celsius. Explain how much energy (in kilojoules) is released during combustion?
As well as how much energy (in kJ) would be released by the combustion of 3.50 g of the same mixture?
