What weighs more…A pound of lead or a pound of feathers?

There is a relationship between an objects mass and its volume.

Density: the ratio of mass of an object to its volume.

Density =Mass

Volume

Page 3: Density. What weighs more… A pound of lead or a pound of feathers? There is a relationship between an objects mass and its volume. Density: the ratio

A 10 cm3 piece of lead has a mass of 114 g. What is its density?

Density =Mass

Volume

Density depends on the composition of the substance, not on its size

Calculating Density.

A copper penny has a mass of 3.1 g and a volume of .35 cm3. What is the density of copper?

A bar of silver has a mass of 68.0 g and a volume of 6.48 cm3. What is the density of Au.
