A quantity of 1.535 g of methanol (CH3OH) was burned in a constant - volume bomb calorimeter. Consequently the temperature of the water rose from 20.27 degrees Celsius to 26.87 degrees Celsius. If the mass of water surrounding the calorimeter was exactly 1000 g and the heat capacity of the bomb calorimeter without the water was 1.75 kJ/degrees Celsius, calculate the molar heat of the combustion of methanol. The answer is in kJ/mol. I really need someone to explain to me step by step on how to do these types of problems. I'm having a hard time understanding how to do these types of problems.
