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

Question
A well insulated calorimeter containing 100 ml of water was calibrated by dissolving.
known amount of potassium chloride in the calorimeter.
The dissolution of potassium chloride in water can be represented by the equation:
KC(s) + aq-
AH = +17.0 kJ mol
K*(aq) + Cl(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
(express your answer to 2 decimal places)
0.40
kJ *C¹
