3,1 moles of an ideal gas with a molar heat capacity at constant volume of 5,1 cal/(mol∙K) and a molar heat capacity at constant pressure of 7,7 cal/(mol∙K) starts at 317,6 K and is heated at constant pressure to 335,9 K, then cooled at constant volume to its original temperature. How much heat (cal) flows into the gas during this two-step process? Answer in two decimal places.
