1a) Consider the reaction: C12H22O11(s)+12O2(g)→12CO2(g)+11H2O (l) in which 10.0 g of sucrose, C12H22O11, was burned in a bomb calorimeter with a heat capacity of 7.50 kJ/∘C. The temperature increase inside the calorimeter was found to be 22.0 ∘C. What is the heat of this reaction per mole of sucrose?

1b) One tablespoon of peanut butter has a mass of 17.0 g. It is combusted in a calorimeter whose heat capacity is 110 kJ/°C. The temperature of the calorimeter rises from 21.6 ∘C to 25.8 ∘C . What is the caloric content of peanut butter in Cal/g?

1c)When a 3.50 g sample of liquid octane (C8H18) is burned in a bomb calorimeter, the temperature of the calorimeter rises by 26.7 ∘C. The heat capacity of the calorimeter, measured in a separate experiment, is 6.10 kJ/∘C . The calorimeter also contains 3.00 kg of water, specific heat capacity of 4.18 J/g°C. Determine ΔErxn for the combustion of octane in units of kJ/mol octane.
