Question 1

Calculate the freezing point of a solution of 500.0 g of ethylene glycol (C2H6O2) dissolved in 500.0 g of water. Kf = 1.86 °C m-1 and Kb = 0.512 °C m-1.
◦ -30.0 °C
◦ 8.32 °C
◦ 30.0 °C
◦ 70.2 °C
◦ -8.32 °C

Question 2

Choose the solvent below that would show the greatest boiling point elevation when used to make a 0.10 mol kg-1 nonelectrolyte solution.
◦ CHCl3, Kb = 4.70 °C m-1
◦ CH3CH2OH, Kb = 1.99 °C m-1
◦ CH3CH2OCH2CH3, Kb = 1.79 °C m-1
◦ C6H6, Kb = 5.12 °C m-1
