PART 2: Calculating Density (include proper units with your answers)

1. Find the mass of your empty graduated cylinder. Record it here:______

2. Use the balance and graduated cylinder to find the mass of 20.0 ml of solution A. record

the mass of solution A in the chart below (don’t forget to subtract the empty graduated

cylinder amount).

3. Calculate the density using the formula: mass/volume and record your answer to the

proper amount of significant digits and record in the chart below.

4. Pour the 20 ml of liquid A back into beaker A and rinse out the graduated cylinder.

Shake out the excess liquid as best as possible (don’t bother with paper towels as you will

never get them back out of the graduated cylinder).

5. Now pour 20 ml of liquid B into the graduated cylinder and measure its mass. Record in

the chart below.

6.Calculate the density of liquid B (to proper amount of significant digits) and record in the

chart.

7. Pour liquid B back into the beaker B. Rinse and shake out the graduated cylinder as best

as possible

8. Pour 20 ml of liquid C into the graduated cylinder. Measure its mass and record it below.

Then calculate its density to proper significant digits and record it below

9. Pour liquid C back into beaker C

10. At the top of each column in the chart, record the units

Liquid

Mass in _____

Volume in ____

Density in ______

20.0

Look at the calculations of your densities and compare it to your results from Part 1. Did

you end up with the same sequence as you did in part 1?

. If the order doesn’t match,

you did something wrong. What could be a source of your error? Why might the results not

match up?(be specific)

Part 3 Density of an object (use proper units with your answers and make sure each

answer has the correct number of significant digits)

1. First find the volume of the cube. Use a ruler to measure the side in cm, then multiply by

length x width x height =

2. Find the mass of the cube. And record here:

3. Calculate the density of the cube

4. Use water displacement method to determine the volume of the fishing lure by filling an

empty graduated cylinder with 20.0 ml of water. Add the lure. The volume is equal to the

change in volume

5. Get the mass of the fishing lure and record it here:

6. Find the density of the fishing lure:
