An automobile antifreeze mixture is made by mixing equal volumes (100. mL) each of ethylene glycol (density = 1.14 g/mL, M.M = 62.07 g/mol) and water (density = 1.00 g/mL, M.M = 18.02 g/mol) at 20 degrees celsius. The density of the solution is 1.070 g/mL. Express the concentration of ethylene glycol in each of the following units of concentration.

a. % by volume, assuming volume is additive

b. Mole fraction of solute and solvent

c. Molality

d. What is the boiling point of this solution of ethylene glycol?
