b. Calculate the mass of Potassium Formate (Molar Mass: 84.12 g/mol) needed to de-ice a 3200 m long by 80 m wide runway by lowering the freezing point by 1 degree °C. Assume a 3 mm height for the intended thickness of the layer along the runway. Report your mass in metric tons and 2 decimals. (Hint: assume a van't Hoff factor of 2 for Potassium Formate). Kf=1.86°C-kg/mol, density = 0.997 g/cm³. Show your work.
