1. Density

2. Density Definitions: Mass per unit volume
How much matter is in a given space.
D = m/v
Mass – the amount of matter
Volume – how much space.

3. Mass vs. Weight If you go to the moon, what happens to mass and weight?
Stays the same. Mass is a measure of the amount of matter.
Changes Weight is measure of gravitational pull.

4. Which Sample Below is more dense?

5. Which liquid is most dense? Which liquid is least dense?

6. To Find Density:
Measure the mass (in grams) using a triple beam balance.
- If your sample is in a container, remember to subtract out the container’s mass.
2) Measure the volume (in milliliters for liquids and cubic centimeters for solids).
length x width x height for rectangles
For irregular shaped objects, measure the amount of water it displaces in a graduated cylinder.
3) Divide the mass by the volume.
