Question

It's January in Nashville and your local weather station just informed you that the temperature outside is -9.55 degrees Celsius. You estimate the amount of ice on your driveway to be approximately 30.0 kg. What is the minimum amount of sodium chloride in kilograms (kg) needed to lower the freezing point of the water so that the ice melts? **Ignore the Van't Hoff Factor for this problem! *Kf = 1.86 °C/m for water *NaCl = 58.44 g/mol
