    hi roger sorry but I want to ask you about a question and I don't know how

    its about enthalpy

    The internal energy change when 1 mole of CaCO3 in the form of calcite converts to aragonite is +0.21kJ. Calculate the difference between the enthalpy change and the change in internal energy when that the pressure is 1.00 bar given that the densities of the solids are 2.71 g.cm-3 and 2.93 g.cm-3 respectively.

    hope you answer this question

    sorry for annoying u.
