Problem: Consider the heating curve shown below for 22.86 grams of an unknown substance. You may assume constant pressure conditions. Note: the points are labeled as (amount of heat added, temperature). Calculate the heat capacity at constant pressure, C p, (in J/mol∙K) for the gas. Show all work and circle your final answer. The moles were identified to be 0.496 mol.
