5. 75.0 mL of distilled water at 28.00 °C was mixed in a calorimeter with 55.0 mL of distilled water at 40.00 °C. The final temperature of the mixture was 34.00 °C. Determine the calorimeter constant, Kcal. The specific heat of water is 4.184 J/g °C. 6. A 5.00 gram sample of ammonium chloride was dissolved in 100.00 grams of water. Using the calorimeter constant of Kcal 25.0 J/oC, how much heat is prod uced by the dissolution (absorbed from the solution) if the temperature goes from 22.0 °C to 2.0 °C. Assume the specific heat of the solution is 4.18 J/g °C. 7. 80.0 mL of a 1.500 M NaOH solution was mixed with 80.0 mL of a 1.500 M HCI solution in a calorimeter. Both the solutions were at the same temperature initially. Using the calorimeter constant of Kcal 15.5 J/oC, determine the heat of the reaction, in kJ/mole, if the temperature goes from 7.0 °C to 29.0 °C. The specific heat of the solution is 4.18 J/g °C. Assume a density of 1.00 g/mL. 246
