#12. Density Problems 2

5. Object A Object B Object C
Group Work: Solving for Density Calculate the densities of the following objects. Remember to place units after each number. Show your work. Be ready to explain. Put the Objects in order from least dense to most dense.
Object A
Object B
Object C
Length= 10 cm
Width= 5 cm
Height= 2 cm
Mass= 300 g
Volume= __________
Density= __________
Length= 6 cm
Width= 3 cm
Height= 1 cm
Mass= 36 g
Length= 5 cm
Width= 1 cm
Mass= 50g

6. Answer the items on the Density Problems #2 Worksheet.
I can calculate the density of an object given its mass and volume.

7. The following liquids were spilled into the tank:
•a green liquid that has a volume of 48 mL and a mass of 36 g
•a blue liquid that has a volume of 144 mL and a mass of g
•a red liquid that has a volume of 96 mL and a mass of g
•a black liquid that has a volume of 120 mL and a mass of 96 g
1. Calculate the density of each liquid. Show your work! Don’t forget the units.
Green liquid: 36 g / 48 mL = .75 g/mL
Blue liquid: g / 144 mL = .90 g/mL
Red liquid: g / 96 mL = 1.2 g/mL
Black liquid: 96 g / 120 mL = .80 g/mL
I can calculate the density of an object given its mass and volume.

8. First (bottom): Red Liquid Second: Blue Liquid Third: Black Liquid
2. Determine the order in which the liquids have settled in the tank.
First (bottom): Red Liquid
Second: Blue Liquid
Third: Black Liquid
Fourth (top): Green Liquid
3. What kind of property did you use to distinguish among these four chemicals?
a chemical property C. a liquid property
a physical property D. a natural property
I can calculate the density of an object given its mass and volume.

9. 4. Use colored pencils to color each layer and label the position of the layers in the tank on the diagram shown below.
Green
Black
Blue
Red
Now that you know where the red chemical is inside the tank, how would you remove it?
You would use the drain at the bottom of the barrel to drain the liquid out since it is on the bottom with the greatest density.
I can calculate the density of an object given its mass and volume.
