A 100 mL sample of 0.300M NaOH is mixed with a 100mL sample of 0.305M HNOs in a coffee cup calorimeter (constant pressure). If both solutions were initially at 35 C and the temperature of the resulting solution was recorded as 37°C, determine the Hrxn (in units of KJ/mol of the limiting reactant). Assume that no heat is lost to the calorimeter or the surroundings. Assume that all of the solutions have specific heat capacity and density of 4.186 /g.°C and 1 g/mL respectively.
