Calcium chloride (1.14 g) is completely dissolved in 100.0 mL of water at 27.00 °C in a ‘coffee cup’ calorimeter. The temperature of the water after dissolution is 28.97 °C. What is the standard enthalpy of solution of CaCl2 (in kJ mol–1). The density of water at 27.0 °C is 0.997 g mL–1 and its heat capacity is 4.184 J K–1 g–1

How many millimeters of water at 25 degrees C with a density of 0.997 g/mL must be mixed with 176 mL of coffee at 96.2 degrees C so that the resulting combination will have a temperature of 61.8 degrees C? Assume that coffee and water have the same density and the same specific heat (4.18J/g. degree C) across the temperature range.
