250.0 mL of 0.300 M HCl is added to 250.0 mL of 0.300 M NaOH in a coffee cup calorimeter. The neutralization reaction that occurs is: HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l) Before the solutions are mixed they are both at 24.52oC. After mixing the solutions the temperature increases until it remains constant at 26.58oC. Assuming no heat lost to the surroundings, how much heat was given off by this reaction (in joules)? (Assume the specific heats and densities of the solutions are the same as water, 1.00 g/mL)

Question
250.0 mL of 0.300 M HCl is added to 250.0 mL of 0.300 M NaOH in a coffee cup calorimeter. The neutralization reaction that occurs is:
HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)
Before the solutions are mixed they are both at 24.52oC. After mixing the solutions the temperature increases until it remains constant at 26.58oC. Assuming no heat lost to the surroundings, how much heat was given off by this reaction (in joules)? (Assume the specific heats and densities of the solutions are the same as water, 1.00 g/mL)
