hello, please answer question #4 about bomb calirometer. dony understand it. thank you!

Bram burned? rather than calories 4. (3 pts) 1.150 g of sucrose goes through combustion in a bomb calorimeter lfthe temperature rose from 23.42Â°C to 27.64Â°C and the calorimeter constant was 4.90 kl/oc, determine the heat of combustion of sucrose in kl/mol.

b) Verify the claim of sugar producers that one teaspoon ofsugar (about 4.8g) contains only 19 calories.

At constant volume, the heat of combustion of a particular compound is â3936.0 kJ/mol. When 1.107 g of this compound (molar mass = 111.78 g/mol) was burned in a bomb calorimeter, the temperature of the calorimeter (including its contents) rose by 8.299 Â°C. What is the heat capacity (calorimeter constant) of the calorimeter?
