Determining the Density of Tomato Juice


Purpose: To determine the density of tomato juice.

Materials and Methods:

  1. Determine the mass of an empty graduated cylinder.

  2. Add 5 mL of tomato juice to the graduated cylinder and determine the mass of tomato juice + graduated cylinder.

  3. Add another 5 mL (total = 10 mL) of tomato juice to the cylinder and determine the mass of tomato juice + graduated cylinder.

  4. Add another 5 mL (total = 15 mL) of tomato juice to the cylinder and determine the mass of tomato juice + graduated cylinder.

  5. Determine the mass of tomato juice only for step 2-4 and then find the density (show all your work in the table).

Observations:

Questions: (Answer on a separate page. Show all your work.)

  1. Calculate the average density for your tomato juice sample.

  2. An empty graduated cylinder has a mass of 55 g. When 27 mL of an unknown liquid is added the mass of the graduated cylinder + liquid is now 108 g. Calculate the density of the unknown liquid.
