50.0mL of a solution of HCl is combined with 100.0mL of 1.15 M NaOH in a calorimeter. The reaction mixture is initially at 22.4 degrees C and the final temperature after reaction is 31.2 degrees C. What is the molarity of the HCl solution? ( Assume that there is an excess of base (so all of the HCl has reacted), that the specific heat of the reaction mixture is 0.96 cal/g degrees C, and that the density of the reaction mixture is 1.02 g/mL. The heat of neutralization of HCl and NaOH is 13.6 kcal/mol.)
