Density Practice

The dots in the cubes below represent the amount of mass each one of them. Which of the following objects is denser and why?

• right cube because it has more mass.

• right cube because it has more mass per volume

• left cube because it has less mass.

• left cube because it has less mass per volume

Given the following information:

Mass of substance A = 10.00 grams

Mass of Substance B = 18.00 grams

Based on the information above, which substance is denser?

• Substance A

• Substance B

• Equal density

• Impossible to tell without information about the volume.

Based on the diagram below, rank the three objects from least dense to most dense.

• Object Z, Object Y, Object X

• Object X, Object Z, Object Y

• Object Y, Object X, Object Z

• Object X, Object Y, Object Z

An object is most likely to sink in water ( D= 1.0 g/mL) if it has a density ___________ than 1.0 g/mL.

• smaller

• larger

• impossible to say

Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1

• 1, 2, 3, 4

• 3, 4, 2, 1,

• 4, 3, 1, 2
