please anwser all padts of question

The specific heat of toluene, C7H8, is 1.13J/gK. How many joules of heat are needed to raise the temperature of 40.0g of toluene from 10.4C to 28.0C ? b When a 4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0C to 16.9C. Calculate H (in kJ/mol NH4NO3 ) for the solution process NH6NO3(s)NH4+(aq)+NO3(aq) Assume that the specific heat of the solution is the same as that of pure water. C A 1.800g sample of octane, CyH1k, was burned in a bomb calorimeter whose total heat capacity is 11.66kJ/C. The temperature of the calorimeter plus contents increased from 21.36C to 28.78C. What is the heat of combustion per gram of octane? per mole of octane
