A chemist carefully measures the amount of heat needed to raise the temperature of a 0.85 kg sample of C H,N from 44.7 C to 62.2 C. The experiment
shows that 3.18 104 J of heat are needed. What can the chemist report for the molar heat capacity of C_H,N? Be sure your answer has the correct number of significant digits.
