1. Density

2. Density- the measure of how much mass is contained in a given unit of volume.
Abbrev. Ending Unit
Density D g/cm3
Mass m g
Volume V cm

3. Density Column-Think about it???
List the following in order of density (from the heaviest to the lightest).
Water, Dawn Dish Soap, Vegetable Oil, Rubbing Alcohol, Karo Syrup, Honey and Lamp Oil

4. Material

Lamp Oil
.80
Vegetable Oil
.92

1.33
Honey
1.42

5. Density Column
What order of density for the following:
Water, Dawn Dish Soap, Vegetable Oil, Rubbing Alcohol, Karo Syrup, Honey and Lamp Oil

6. To find density of an object, you need the mass and volume of the object.
1. Mass- remember to use the balance.
2. Volume- there are 2 ways to find the volume of objects.

7. a. To find the volume of a circular object use a graduated cylinder.
-Measure some water in a graduated cylinder
-Drop the object and reread the graduated cylinder
Subtract the two numbers....you should always have a positive number.

8. 60 mL = 60 cm3 200 mL 260 mL Water Water with Coin
Calculate the volume of the coin.
260 mL – 200 mL = 60 mL
60 mL = 60 cm3
200 mL mL
Water Water with Coin

9. b. To find the volume of a rectangular object use a ruler.
Volume = Length X Width X Height cm3 cm x cm x cm
2 cm
2 cm
1 cm
2 cm X 1 cm x 2 cm = 4 cm3

10. What is the volume of the box??
3 cm
5 cm
2 cm
5 cm X 2 cm X 3 cm = 30 cm3

11. D = m / v
m = D x v
v = m / D m : : X D V

12. D = m / v v = m / D Ex: m = 2 g v = 1 cm3 D = 2 g/ cm3 Ex: m = 6 g

13. Ex: m =
v = 1cm X 2cm X 4cm
D = 2 g/cm3
m = 16 g
v = 8 cm3
m = D x v
