During the 9.9 SALE, Otis purchased 1.0 gallon (4.55 L) of antifreeze containing 3.78 L of ethylene glycol for his race car. Assuming that the antifreeze solution only contains ethylene glycol and water, calculate for the following values. Physical Properties Ethylene Glycol 62.068 Water Molar mass, g/mol Density, g/mL Freezing point, °C Freezing point constant (K:), °C/m 18.016 0.9970 1.1156 0.00 1.86 -12.9 3.11 1. Calculate the molality of the antifreeze solution. 2. Determine the temperature at which the antifreeze solution will start to freeze. 3. According to Mang Tani, the temperature for October will drop to -10°C. Will the antifreeze solution protect the race car engine this month?
