When 0.320 moles of NH4Cl is dissolved in 1.00 L of water, the temperature drops by 13.7 degrees C. What is the heat of solution of ammonium chloride? The solution has a density of 1.0012 g/mL and a specific heat of 0.9818 cal/g degrees C.

    q = mass water x specific heat water x delta T.
    Use density to determine mass water.
    delta H soln = q/0.320 for cal/mol

    can you be more specific? that equation does not make any sense.
