A chemist carefully measures the amount of heat needed to raise the temperature of a 1.28 kg sample of C H2S from -2.7 °C to 15.3 °C. The experiment shows that 4.60 x 10' J of heat are needed. What can the chemist report for the molar heat capacity of C, H,,S? Round your answer to 3 significant digits.
