Solve the given problems:
Problem 1: 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. How many kilocalories per gram are there in a 3.41-g brazil nut if the energy from burning it is transferred to 0.420 kg of water held in a 0.110-kg aluminum cup, causing a 53.7 ºC temperature increase? Units are in kcal/g.
Problem 2: If a serving of Brazil nut consists of 14 g, how many kcal is consumed per serving? (Note: food packaging energy content is labeled as "cal" which is equivalent to "kcal".) Units are in kcal
