Think about a plan….

What is density? Mass? Volume?

Density: the amount of matter, or mass, per unit volume

Mass: the amount of matter an object has

Volume: the amount of space an object occupies

Volume & Density

D = mass

volume

OR

M = D•V

Example 1 What is the density of a piece of wood that

has a mass of 25.0 grams and a volume of 29.4 cm3 ?

Example 2 A piece of wood that measures 3.0 cm by

6.0 cm by 4.0 cm has a mass of 80.0 grams. What is the density of the wood?

Example 3 A cup of gold colored metal beads was measured to

have a mass 425 grams. By water displacement, the volume of the beads was calculated to be 48.0 cm3. Given the following densities, identify which metal it is!

Gold: 19.3 g/mL Copper: 8.86 g/mL Bronze: 9.87 g/mL

Example 4 What is the mass of a cylinder of lead that is

2.50 cm in diameter, and 5.50 cm long. The density of lead is 11.4 g/mL and the volume of a cylinder is 6.

Example 5

Partner Race!! A little aluminum boat (mass of 14.50 g) has a volume of

450.00 cm3. The boat is place in a small pool of water and carefully filled with pennies. If each penny has a mass of 2.50 g, how many pennies can be added to the boat before it sinks?

Recall---- Get a highlighter, we will walk through the

explanation & two examples on the paper Highlight important information Mrs. Sawyer will randomly call on people to

read!

Homework Work on the problems on the back and fill

in the chart. When done, complete the HW on your

OWN paper. DO NOT try to fit on the small sheet. Keep that sheet for notes.
