Read each question carefully and provide the best answer. Show all your calculations where applicable.
1. Which of the following is the most common unit for expressing the concentration of a solution?
Molality
Molarity
Mole fraction
Percent by mass
2. What happens to the molarity of a solution when more solvent is added?
It increases
It decreases
It remains the same
It depends on the solute
3. Molarity is defined as moles of solute per of solution.
4. A solution with a high concentration of solute is described as .
5. Calculate the molarity of a solution prepared by dissolving 25.0 g of NaOH (molar mass = 40.00 g/mol) in enough water to make a 500 mL solution.
6. Describe the difference between a concentrated and a dilute solution. You may use the image below as a visual aid.
7. Increasing the temperature generally decreases the solubility of solids in liquids.
True
False
8. Molality is temperature-dependent.
True
False
Match each term with its correct definition.
9. Solute
a. The component present in the largest amount in a solution.
10. Solvent
b. A homogeneous mixture of two or more substances.
11. Solution
c. The component present in a smaller amount in a solution.
