1. if 100.0 grams of ethylene glycol are dissolved in 900.0 grams of water, what is the freezing temperature of the solution formed? follow these steps: show all of your calculations.

calculate the molar mass of ethylene glycol:
62.07 g/mol

calculate the number of moles of ethylene glycol in the solution:

calculate the molality of ethylene glycol:

calculate the freezing point depression using the kf from the chemistry b information sheet and the molality that you calculated:

calculate the freezing point of the solution.

2. think about the result. think about the typical mid-winter temperature we experience in michigan. is this concentration of ethylene glycol high enough to use in a car radiator in the winter? why or why not?
