**Problem Statement:**Ethylene glycol (C₂H₆O₂; MW = 62.06844 g/mol), the main component of antifreeze, must be added to 5.0 L of water to produce a solution for use in a car radiator that freezes at -23.3 °C. What mass of ethylene glycol (kg) should be added to the water? Assume dₐwₐₜₑᵣ = 0.9995 g/mL. Give your answer in the blank with the appropriate number of significant figures.**Explanation:**To solve this problem, you'll need to consider principles of freezing point depression, where the addition of a solute lowers the freezing point of a solution. Calculations will require using the density of water to convert the volume to mass, the molecular weight of ethylene glycol to convert between mass and moles, and applying the freezing point depression equation.

c) To save money, some state Department of Transportation decided to replace relatively expensive calcium chloride (CaCl2) by more affordable beet juice (mostly made of sugar molecules) in the solutions used to treat the roads before a snow/freezing rain storm. However, the beet juice was not as effective at de-icing the roads as was the calcium chloride solution. When road temperatures were very low, the beet juice treatment did not prevent the water from freezing again. You are called to one of those Departments of Transportation to: 1) Explain that observation and 2) Justify why they should continue to use calcium chloride solutions even if it is more expensive. You may even suggest a cheaper alternative to calcium chloride that will be as effective in road de-icing. Provide your answers below.
