1. Density

2. Density A measure of the amount of mass in a certain volume or space
Density is a ________ property of matter
Density of an object stays the same
Density
physical

3. Density is usually expressed as grams per cubic centimeter; g/cm3 OR as grams per milliliter; g/mL
Formula:
Density = mass
Volume
D = m V

4. Ice and Water
Ice (0.93 g/cm3)is less dense than water (1 g/cm3), therefore ice floats in water.

5. Density of Water and Oil
Density of Water = 1 g/mL
Density of Oil = 0.92 g/mL
The oil is less dense than the water, therefore the oil floats on top of the water.

6. Example
What is the density of a can of soda that has a volume of 100 mL and a mass of 150 g?
Step 1: Equation
Step 2: Substitute
Step 3: Solve
D= M V
D= 150g
100 mL
D= 1.5 g/mL

7. The volume of a cup of oil is 50 mL and it’s mass is 75 g
The volume of a cup of oil is 50 mL and it’s mass is 75 g. What is the density of the cup of oil?
