Derived Properties of Matter
Properties of matter can be directly measured or
they may be derived from a combination of
other measured properties.
One such property that is derived is density and
other is some cases is volume.
Take a moment to write down everything you
can recall about density and volume.
Volume
How do you measure volume?
Volume is the total space occupied so you can
measure it by measuring length, width, and
height. Then multiple them together.
Volume is length * width * height
cm*cm*cm = cm3
But what if the object is not a standard shape?
Use the water displacement method.

Density
Density is a ratio between the amount of mass
and the total space it occupies.
Density units will include a mass unit on top and
a volume unit on the bottom.
Examples: g/mL, kg/L, g/cm3
Density Problem 1
Calculate the mass of a liquid with a density of
3.2 g/mL and a volume of 25 mL.
Density Problem 2
An irregular object with a mass of 18 kg
displaces 2.5 L of water when placed in a large
overflow container. Calculate the density of
the object.
Density Problem 3
The density of silver (Ag) is 10.5 g/cm3. Find the
mass of Ag that occupies 965 cm3 of space.
Each layer represents a
different liquid
chemical.
