22. Which liquid layer has the smallest density?

23. Which is denser, the green or yellow layer? Explain.

24. Calculate Density
Mass = 400g
Volume = 100 cubic centimeters

25. Calculate Volume
Bob has measured the sides of a box. It has the following dimensions:
Height = 4cm
Length = 2cm
Width = 2cm

26. Calculate Density A box on a triple-beam balance measures 48g.
The box has the following dimensions:
4cm x 3cm x 2cm

27. Put the following substances in order as they would appear in a density column.
Corn Syrup- 1.3g/ml
Engine Oil g/ml
Mountain Dew- 1.1g/ml
Rubbing Alcohol g/ml

28. Calculate Density (D=m/v)
Blair places an object on a triple beam balance. It reads 45g.
Blair uses water displacement and the water changes from 20mL to 25mL
What is the density of the object?

29. Will the object below float in water that has a density of 1.0g/mL?
Mass: 100g
Volume: 25mL

30. Which phase has definite volume but not shape?

31. Calculate Density (D=m/v)
Mass = 15g
Volume = 3mL

32. Calculate Density (D=m/v)
Mass = 55g
Volume = 5mL

33. Calculate Volume (V=M/D)
Density = 3g/mL
Mass = 12g

34. Calculate Mass (M=D*V)
Density = 3g/mL
Volume= 10mL
