Ethylene glycol (OH—CH2—CH2—OH) is used as an antifreeze. (Its boiling point is 197 ◦C and freezing point is –17.4 ◦C.)(a) Look up the density of ethylene glycol in the CRC Handbook or other tables and write a general formula for the freezing point of a mixture of X mL of ethylene glycol in 1.00 L of water for X in the range 0–100 mL.(b) If the lowest expected temperature is about –10 ◦C, what is the minimum amount of ethylene glycol (milliliters ethylene glycol per liter of H2O) you need in your coolant?(c) What is the boiling point of the coolant that contains 300 mL of ethylene glycol per liter of water?
