Specific Molar Mass

  1. May 13, 2007 #1
    1. The problem statement, all variables and given/known data

    From Q=m*Cp*(change in temperature), they give me all but Cp, which I calculate, and they also give me a mass per mole of the substance. Now the next part of the problem asks for the molar specific heat of the substance, but the equation for this eludes me.

    2. Relevant equations



    3. The attempt at a solution

    So you've calculated the heat capacity per mass? Convert your heat capacity per mass into heat capacity per mol. Look at the units to see. You will just multiply your answer by the molar mass.

    Or, do the calculation again, this time convert the mass given into moles

    #moles = (mass in grams) / (molar mass in grams per mole)

    and solve for Cp.

    Either way.
