To determine the volume of the sample, you need to determine how much water was displaced. To do this, you subtract the initial, or beginning, volume from the final volume. How much water was displaced? If you need help click on the word "Hint" below.
When we use the water displacement method to find the volume of an object, we must convert the units from milliliters (mL) to centimeters cubed (cm3). 1 mL = 1 cm3. So in our example above, 22 mL = 22 cm3.
Now, let’s determine the density of the unknown sample. We know the volume is 22 cm3. Let’s find the mass. Drag the sample onto the electronic balance to determine the mass.
0.00 g
Well Done!
Incorrect
Plug the volume and mass into the density formula. Density =
m over vmv
Density =
55.8 over 2252.822
