1. Molarity is defined as the number of of solute per liter of .
2. The formula for molarity (M) is / .
3. Which of the following pieces of laboratory equipment would be most appropriate for accurately preparing a solution of a specific molarity?
Beaker
Volumetric flask
Graduated cylinder
Test tube
4. Calculate the molarity of a solution prepared by dissolving 2.5 moles of NaCl in enough water to make 500 mL of solution.
5. How many grams of glucose (C6H12O6) are needed to prepare 2.0 L of a 0.50 M glucose solution? (Molar mass of C6H12O6 = 180.16 g/mol)
6. Increasing the amount of solvent always increases the molarity of a solution.
True
False
7. Molarity is temperature-dependent because volume changes with temperature.
True
False
8. Describe how you would prepare 250 mL of a 0.10 M NaOH solution in the lab, starting from solid NaOH.
