Question

A hemoglobin molecule (molar mass =65000 g) can bind up to 4 oxygen molecules. In a certain experiment a .085-L solutoin containing 6.0 g of deoxyhemoglobin was reacted with excess of oxygen in a constant-pressure calorimeter of negligible heat capacity. calculate the enthalpy of the reaction per mole of oxygen bound if the temperature rose by .044 degree celcius. (specific heat of solution is equal to that of water)
