1.50 g of sucrose (C12H22O11) is placed in a bomb calorimeter. The bomb calorimeter has a heat capacity of 8.57 kJ/oC. The temperature of the calorimeter changes from 25.00oC to 27.88oC. What is the molar enthalpy of combustion of sucrose?

Answer:
in a bomb calorimeter q = delta E first calculate the heat absorbed by calorimeter heat absorbed = (final temperature - initial temperature) * heat capacity Qcalorimeter + Qreaction = 0 Qreaction = -Qcalorimeter next convert the grams into moles use this equation to find molar enthalpy of combustion Q = n * deltaH u have q and n plug in your values and youll get deltaH
