Experiment 2: Volumetric Measurement of Liquid

What is measured with a graduated cylinder?

• Passage of time

• Weight of an objec

• Distance from one thing to another

• Volume of liquid

What is the measurement for the meniscus on the graduated cylinder in the figure?

• 780 mL

• 7.8 L

• 775 mL

• 770 mL

When you make a dilution, which of these values remains constant?

• The molarity (M)

• The total moles of solute

• The volume (V)

• The concentration

• 0.625 g NaCl

• 36.5 g NaCl

• 625 g NaCl

• 0.04 mol NaCl

What is the molarity of a solution made by diluting 26.5 mL of 6.00M HNO₃ to a volume of 250 mL?

• 15.9 M
