You need to prepare 200ml of a 0.4M solution of copper sulfate (CuSO4). You have 80mL of a 0.5M CuSO4 solution and 100ml of 7.5% (w/v) CuSO4 solution. What volume of 7.5% CuSO4 and water needs to be added to the 80mL of 0.5M CuSO4 solution to make up 200mL of 0.4M CuSO4? Molar mass of CuSO4 = 159.609 g/mol % (weight/volume) means mass (in g) in volume (100mL)

The salt copper(II) sulfate is soluble in water. When 2.19 g CuSO4 is dissolved in 102.00 g water, the temperature of the solution increases from 25.00 °C to 27.28 °C. Based on this observation, calculate the dissolution enthalpy, ΔdissH, of CuSO4. Assume that the specific heat capacity of the solution is 4.184 J g-1 °C-1 and that the energy transfer to the calorimeter is negligible.
