Colligative Properties of Non–Electrolytes

1. A mixture which contains 0.550 g of camphor and 0.045 g of an organic solute freezes at 157.0 °C. The
solute contains 93.46 % of C and 6.54% of H by weight. What is the molecular formula of the compound?

2.An aqueous solution contains 20 g of glucose per liter. Assuming the solution to be ideal, calculate the
osmotic pressure at 25°C.

Colligative properties are those that depend on the number of solute particles. Because electrolytes dissociate into ions, the concentration of particles in the solution is greater than the formula-unit concentration of the solution. For example, if 1 mol of Na2SO4 totally dissociates, 3 mol of ions are produced (2 mol of Na+ ions and 1 mol of SO42−ions). Thus, a colligative property such as osmotic pressure will be three times greater for a 1 MNa2SO4 solution than for a 1...

Camphor has a melting point of 178.4℃ and a Kf of 37.7℃/m. If 0.550 g of an unknown nonelectrolyte lowered the freezing point of 35.0 g of camphor by 2.00℃

A) Camphor has a melting point of 178.4℃ and a Kf of 37.7℃/m. If 0.550 g of an unknown nonelectrolyte lowered the freezing point of 35.0 g of camphor by 2.00℃, what was the molar mass of the unknown? B) When 1.00 g of hemoglobin is dissolved in enough water to form 100mL of solution, the osmotic pressure at 20℃ is 3.62x10-3 atm. What is the molar mass of the protein, hemoglobin?
