A well insulated calorimeter containing 100 ml of water was calibrated by dissolving a known amount of potassium chloride in the calorimeter. The dissolution of potassium chloride in water can be represented by the equation: - K²(aq) + Cr(aq) AH +170 kJ mol KC(s) aq The temperature of the calorimeter was initially 18.00 °C. A sample of 2.46 g of potassium chloride was dissolved in the 100 ml, and the temperature was recorded as 16.60 °C. The calibration factor of the calorimeter is kJ *C-¹ (express your answer to 2 decimal places) 040
