Compute all parts of given question:

Question: The number of kilocalories in food is determined by calorimetric techniques in which the food is burned and the amount of heat transfer is measured.

Part A: How many kilocalories per gram are there in a 3.03-g walnut if the energy from burning it is transferred to 0.420 kg of water held in a 0.092-kg aluminum cup, causing a 45.7°C temperature increase?

Part B: If a serving of walnut consists of 16.0-g, how many kcal is consumed per serving?

Please show all work and steps I am really trying to learn this for my test.
