- 18. kJ/molrxn 0.250 grams of solid aluminum are placed in excess solution of copper (II) nitrate and completely react to make a total volume of 100.mL of solution (density = 1.01 g/mL). The temperature of the solution increased from 25 degrees Celsius to 39.1 degrees Celsius. Assuming the specific heat capacity of the solution is 4.18 J/g C, calculate the change in enthalpy in kJ/molrxn.
