I need help with number 2

Please help me with this question. Answer with full detailed step by step solutions, no cursive handwriting. Show all your work! Thanks! Copper (II) sulfate reacts with sodium hydroxide in a double displacement reaction.  The equation for the reaction is : CuSO4(aq). + 2NaOH(aq)--> Cu(OH)2(aq). + Na2SO4(aq). 50.0 mL of 0.300 mol/L copper(II) sulfate is mixed with an equal volume of 0.600 mol/L sodium hydroxide. The initial temperature of both solutions is 21.4 C.  After mixing the solutions in the calorimeter, the highest temperature that is reached is 24.6 C. Determine the enthalpy change of the reaction in KJ/mol of copper (II) sulphate.  Then write the thermochemical equation.
