2. Draw a beaker with white dots representing a solvent and filled in dots representing the solute

3. State three types of concentration

4. Write the formulas for molarity and molality, and state the difference between the two

5. Find the molarity of a solution that contains 35 grams of K2SO4 in 5 L of solution.

6. What mass of KOH is needed to make 5 L of a 0.25M solution?

7. Find the molality of a solution containing 85 grams of MgF2 dissolved in 100 grams of water.

8. Draw one beaker that appears to contain an unsaturated solution, and another beaker that most likely contains a saturated solution

9. On the solubility graph under number 6, label: -The supersaturated region of kcl with an “A” -The saturated region of kcl with a “B” -The unsaturated region of kcl with a “C”

10. Determine the solubility of NaCl at 100 degrees celsius

11. Determine the solubility of kcl at 60 degrees celsius

12. What is the minimum temperature needed to make a saturated solution using 30 grams of kno3?

13. What is the minimum temperature needed in order to dissolve 75 grams of cacl2 in 100 grams of water?

14. Which solute is a gas? How do you know?

15. What kind of solution would you have if you dissolved 40 grams of nacl at 100 degrees Celsius?

16. What mass of kno3 can be dissolved in 50 grams of water at 20 degrees Celsius?

17. How much water is required to dissolve 35 grams of k2cr2o7 at 90 degrees Celsius?

18. What are the two colligative properties we covered
What are the two colligative properties we covered? And what are they dependent on?

19. Draw two beakers, with one holding just water, and another containing a solution of sugar water.
Label the beakers with the higher boiling point/lower boiling point.
Label the beakers with the higher freezing point/lower freezing point.

20. Find the boiling point of a solution that contains 44 grams of glucose dissolved in 350 grams of water.

21. An aqueous solution (dissolved in water) of glucose has a freezing point of -2.15oC. What is the molality of this solution?
