Please, I need a step-by-step guidance on how to solve this:

The temperature rises from 25°C to 29° in a bomb calorimeter when 3.50g of sucrose undergoes combustion in a bomb calorimteter. Calculate the heat of combustion of sucrose in kJ/mol sucrose. The heat capacity of the calorimeter is 4.90 kJ/°C. The molar mass of sucrose is 342.3g/mol.

I need to use $q=mc \Delta T$ right?

owlet · Answer

If I use it..

$q=mc \Delta T\q=(3.5g)(4.90\ kJ/°C)(4°C)\q=68.6\ kJ•g$
