0 3) You have to use as little solvent as possible to dissolve a solute to create a saturated solution. Assuming that you are using an ideal solvent, what should you do to the solvent and solute BEFORE adding the solvent to the solute to achieve the forming of a saturated solution? (4 pts) to a Solvent:

3. What are the solvent and solute activities and activity coefficients for a component having 25% mole fraction and obeying the vapor pressure equation P=78.8x; e (0.65x3 +0.18x})? (Hint: think about Raoult's and Henry's Laws) 4. The Debye-Huckel limiting law is strictly valid only in the limit of infinite dilution. A more widely applicable equation is the Debye-Huckel equation:

Please Explain Explain why a) solute-solute, b) solute-solvent, and c) solvent-solvent interactions are important in determining the extent a solute dissolves in a solvent. What is the relative importance of each of each factor listed in problem #1 when a) solids, b) liquids, and c) gases dissolve in water?

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...

Help with 13
Solution B has greater solute (solute "solute particles") concentration than does solution A. Solution A is hypoosmotic to Solution B. 13. You are instructed to make one liter of 150 mM of NaCI. Given the salt (NaCl) and equipment needed for weighing and measuring volumes, tell exactly how you would make this solution. (show all calculations). What is the osmolarity of this solution?
