Density Math Problems

A bar of copper has a mass of 216g and a volume of 24cm³. What is the density of copper?  

• 9g/cm3
• .11g/cm3
• 5184g/cm3
• 322mL

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

• 2g/cm³
• .5g/cm_³
• 72g/cm³
• 4mL

What is the unit of measurement for mass? 

• mL
• cm³
• g
• g/cm³

The volume of a candy bar is 55cm³. The mass of the candy bar is 70g. What is the density of the candy bar? 

• 2.3g/cm³
• .8g/cm³
• 3850g/cm³
• 1.3g/cm³

To calculate density you would use the following equation

• D = M/V
• M = D x V
• V = M/ D
• NONE OF THESE

If you are given the density and volume of an item, how would you calculate its mass?

• D = M/V  SO..
  M = D/V
• D = M/V  SO...
  M = V/D
• D = M/V SO...
  M = D x V

What is the mass of an rock that has a density of 3.52 g/cc. and when put in a graduated cylinder with 50ml of water makes the level rise to 62ml.
* quick search -what is the rock you have tested?

• 42.24 ml
• 42.24 g
• 12 g
• 12 ml

If you know the density and the mass of an object, what equation would you use to calculate its volume?

• V = D/M
• V = M/D
• V = M x D
• V = l x w x h

What is the volume of an object whose density is 10.5 g/ml and has a mass of 100 grams?
*quick search - what metal is this object?

• V =  105 ml
• V = 1005 ml
• V = 10500 ml
• V = 1050 ml

If you are given a cube of sugar, how could you calculate its volume?

• V = M/D
• V = MD
• V = l x w x h
• V = final water level - initial water level
