The density (d) of a material is its mass (m) divided by
its volume (V). The equation for density is:
Density of Coke vs. Diet
Coke
So how dense is Mercury?
Density would be the same on the Moon
Since density is related to the mass of an object, the density of a given
volume of lead would be the same on both the Earth and the Moon, although
the lead would "weigh" less on the Moon because of the lower
gravity there.

1. Calculate the density for the following
object. If you know that the object has a mass of
20. grams and the volume is 10. ml.
20g/10ml=
2.0g/ml
2. Calculate the volume for the following object
If you know that the object has a mass of
21.0 grams and the density is 12.0 g/ml.
21.0g /(12.0g/ml)=
1.75 ml
3. Calculate the mass for the following object.
If you know that the object has a density of
20.0 g/ml and the volume is 5.00 ml.
20.0 g/ml x 5.00 ml=100.g
4. Calculate the density of a liquid in a beaker.
The beaker has a mass of 15 grams when empty. The beaker plus an
unknown liquid has a mass of
50. grams. What is the density of the liquid if its volume is 10.
mL?
50.g-15g/ 10.ml= 3.5 g/ml
5. Calculate the density of a piece of metal. The
rectangular piece of solid metal has the dimensions of 2.0 cm, 3.0
cm, and 2.0 cm. The unidentified metal has a mass of
40. grams.
