49. 1. Boiling Point Elevation - increase in boiling points with more solute particles in the
solution 2. Osmotic Pressure - Changes in the osmotic pressure with more solute
particles 3. Vapor Pressure lowers - decrease in vapor pressure, increase in solute
particles 4. Freezing Point Depression - Decrease in freezing point, more solute particles.
50. Because the solute particles cause a decrease in vapor pressure above the solution.
Solution boils when vapor is equal to the outside pressure, so the decrease in vapor
requires a higher boiling temp.
51. 0.0936 kilograms were dissolved
52. Boiling point is 100.3 Celsius Degrees, Freezing point is -1.03 Celsius Degrees
95.It is the physical property of a solution which is changed by the number of solute
particles, but not by their nature.
97. Tb is the boiling points and pure solvent differences, while Kb is the constant of
molal boiling point, with m because the molarity.
99. The freezing point is 2.74 Celsius Degrees
100. The new freezing point is -10.5 Celsius
101. The pot should boil at 100.29 Degrees Celsius
102. The amount of (C10H8) required is 703 grams
103. For each kg of Water, 157 grams of Rock Salt is needed
