A cashew is burned in a soda can calorimeter, and heats up 0.245 kg of water by 3.65 °C. The calorimeter was calibrated and had a calorimetry constant of 8.50 kcal/kg·°C. Given that fat contains 9.00 kcal/g, calculate the mass in g of the fat contained in the cashew. Assume that the cashew is composed primarily of fat.
A) 13.2 g
B) 15.8 g
C) 11.5 g
D) 17.4 g
