A coffee cup calorimeter having a heat capacity of 451 J/°C was used to measure the heat evolved when 100 ml of 1 M NaOHao) was added to 20 ml of 5 M HClag) initially at 23.000 °C. The temperature of the water rose to 28.855 °C. Calculate AH, (in kJ/mol) for this reaction. Assume the specific heat of the final solution is 4.184 J/g°C and the density of each solution is 1.00 g/ml. 2. A solution is formed by combining 10 mL of solution A and 40 mL of solution B. Find out the heat of reaction by assuming that no heat is lost to the calorimeter, if the initial and final temperature of the system is 20.4 and 28.5 °C, respectively. Specific heat of a solution is 4.184 J/g°C and density is 1.6 g/ml. 10
