Question 1

All of the following are colligative properties except:

◦ osmotic pressure.
◦ boiling point elevation.
◦ freezing point depression.
◦ density elevation.
◦ none of these are correct.

Question 2

An ideal solution is formed from a mixture of the nonvolatile solute urea, CO(NH2)2, and methanol, CH3OH. The vapor pressure of pure methanol at 20°C is 89 mmHg. If 6.6 g of urea is mixed with 39.3 g of methanol, calculate the vapor pressure of the methanol solution.

◦ 7.3 mmHg
◦ 76 mmHg
◦ 68 mmHg
◦ 21 mmHg
◦ 82 mmHg
