7. If 23:0M solution of glucose (CHO), a 2.0 M solution of Na,$0, and a 1.0 M solution of (NH4)3PO4, is made, which solution will have the lowest vapor pressure, highest boiling point, and lowest freezing point? In Part 1 of this experiment you will determine the freezing point of benzophenone. Ben- zophenone is a solid at room temperature and is completely dissolved at 50°C. By letting the liquid cool and measuring the temperature as a function of time, the...

The freezing point of 53.37 g of a pure solvent is measured to be 49.20 ºC. When 2.74 g of an unknown solute (assume the van 't Hoff factor = 1.0000) is added to the solvent the freezing point is measured to be 47.05 ºC. Answer the following questions ( the freezing point depression constant of the pure solvent is 7.83 ºC·kg solvent/mol solute). What is the molality of the solution? m How many moles of solute are present? mol...

The freezing point of 53.48 g of a pure solvent is measured to be 41.91 ºC. When 2.94 g of an unknown solute (assume the van 't Hoff factor = 1.0000) is added to the solvent the freezing point is measured to be 39.86 ºC. Answer the following questions ( the freezing point depression constant of the pure solvent is 7.33 ºC·kg solvent/mol solute). -What is the molality of the solution?___ m -How many moles of solute are present? ___mol...

You obtained the following
graphical data from two experimental runs to determine the freezing
point depression constant for a pure solvent. The solution was made
up by adding 3.025 g of naphthalene, C10H8,
to 45.320 g of pure solvent.
1.What is the freezing point temperature of the pure solvent (in
oC)?
2.What is the solution freezing point temperature (in
oC)?
3.What is the freezing point depression, Tfp (in
oC)?

What is the relationship between the moles of solute and the
mass of solute?
Rewrite the molality expression in terms of grams and molecular
weight.
Background:
Properties that depend on the concentration of particles in solution are called colligative properties. The number of particles in a solvent can affect the freezing or boiling point of solvent. To express the effect of concentration on freezing point or boiling point, molality is used in place of molarity. Molality (m) is the number...
