Part C A sucrose solution is prepared to a final concentration of 0.140 M. Convert this value into terms of g/L, molality, and mass %. (Use the following values: molecular weight MW sucrose = 342.296 g/mol; density Psol'n = 1.02 g/mL ; and mass of water, mwat=972.1 g). Note that the mass of solute is included in the density of the solution.

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 NazSO4 totally dissociates, 3 mol of ions are produced (2 mol of Nat ions and 1 mol of SO, ions). Thus, a colligative property such as osmotic pressure will be three times greater for a 1 M NazSO, solution than for a 1 M nonelectrolyte solution. Part A Assuming complete dissociation of the solute, how many grams of KNO3 must be added to 275 mL of water to produce a solution that freezes at - 14.5 °C?

What is a colligative property? O A property that depends on the number of particles in solution, but not on the nature of the particles. O A property that relates the temperature of a gas to the pressure of the gas. O A property that depends on the specific chemical behavior of the constituent elements and not on the amount in solution. O A property that can only be measured when the moles of gas are constant. O A property that enhances the solubility of a molecule in water.
