A piece of parmesan cheese is burned in a soda can calorimeter, and heats up 0.235 kg of water by 2.85 °C. The calorimeter was calibrated and had a calorimetry constant of 8.50 kcal/kg・°C. Given that protein contains 4.00 kcal/g, calculate the mass in g of the protein contained in the parmesan. Assume that the cheese is composed primarily of protein.
