A deoxyhemoglobin molecule (molar mass 65,000 g) can bind up to four oxygen molecules. In a certain experiment a 0.065 L solution containing 6.3 g of deoxyhemoglobin (hemoglobin without oxygen molecules bound to it) was reacted with an excess of oxygen in a constant pressure calorimeter of negligible heat capacity. Calculate the enthalpy of reaction per mole of oxygen bound if the temperature rose by 0.011°C. Assume that the density of the solution is 1.00 g/mL and that the heat capacity of the solution is the same as the specific heat of water, 4.184 J/gºC.
