Molar Specific Heat

  1. Jan 25, 2009 #1
    1. The problem statement, all variables and given/known data

    Let 25.2 J of heat be added to a particular ideal gas. As a result, its volume changes from 46.0 to 101.2 cm3 while the pressure remains constant at 1.0 atm. By how much did the internal energy of the gas change?
    19.6 J is the answer which i understand how to get the next question is

    What is the molar specific heat at constant pressure?
    I have tried so many different ways. I dont know if I am doing conversions wrong or not setting it up right. I am pretty sure all my conversions are right.

    2. Relevant equations

    3. The attempt at a solution
