PL Worksheet #4 Colligative Properties 1. Given the K b of acetic acid is 3.07 C/ m and the boiling point is 117.9 Celsius, solve for the boiling point of a solution that has 75 g of Fe(OH) 2 dissolved in 1.85 kg of acetic acid. 2. Diethyl ether has a freezing point of −116.2 Celsius. A solution is made by dissolving CH 2 O into 5 kg of diethyl ether and the solution has a freezing point of −120 Celsius. What mass of CH 2 O was dissolved in the solution? 3. Given the structure of diethyl either is: CH 3 −CH 2 −O−CH 2 −CH 3 , what type of intermolecular forces would exist between it and CH 2 O?
