Calculate Density

The mass of an object is 20g. It is placed in a graduated cylinder that has 8mL of water. The water rises to 10mL of water. What is the object's density?

• 5

• 2

• 10

• 8

Density equals mass divided by volume. What does the "M" stands for in the density equation?

• Mass

• Volume

• Density

• Matter

What is the density of a plastic ball that has a volume of 6cm³ and a mass of 12g? 

• 2

• .5

• 72

• 4

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7

• 28

• 60

• 5

What is the density of an object that has a mass of 25 g and a volume of 10.0 cm³?

• 2.5

• 5.2

• 5

• 2

Jack has a rock. The rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL

• 7 g/cm³

• 28 g/cm³

• 1/7 g/cm³

What two types of measurements make up DENSITY? 

• Mass and Volume

• Temperature and Mass

• Grams and Centimeters

• Volume and Weight

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 

• The bolt because it has sunk to the bottom

• The soda cap because it is not just full of air like the Ping Pong ball

I have two objects with the same volume but different masses.  Which object will be more dense?

• The object with less weight.

• The object with more weight.

• The object with more mass.

• The object with less mass.

A metal cube has a side length of 3 cm and a mass of 81 g. What is its density?
