Density Calculation Practice

To calculate density you would use the following equation

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

If a cube has a mass of 50 grams and a volume of 10cc, what is its density?

• 10/50 = .2 cc/g
• 10cc x 50 g = 500 gcc
• 50g/10cc = 5 g/cc
• not enough information

If a cube has a mass of 50 grams and a volume of 10cc, what is its density?

• 10/50 = .2 cc/g
• 10cc x 50 g = 500 gcc
• 50g/10cc = 5 g/cc
• not enough information

If a cube has a mass of 50 grams and a volume of 10cc, what is its density?

• 10/50 = .2 cc/g
• 10cc x 50 g = 500 gcc
• 50g/10cc = 5 g/cc
• not enough information

A key is placed in a graduated cylinder with 60 ml of water. It makes the water level rise to 67 ml.  What is the volume of the key?

• 60 ml
• 67 ml
• 127 ml
• 7 ml

A key displaces 7 ml of water and has a mass of 59.5 grams. What is its density?
(how could you determine what is it made of??)

• D = M/V  59.5g/ 7ml = 8.5 g/ml
• D = M/V       7/ 59.5 = .117 ml/g
• D = M V =7 x 59416.5 gml

A key displaces 7 ml of water and has a mass of 59.5 grams. What is its density?
( quick search how could you determine what is it made of??)

• D = M/V  59.5g/ 7ml = 8.5 g/ ml
• D = M/V       7/ 59.5 = .117 ml/g
• D = M V =7 x 59.5 416.5 mlg

A key displaces 7 ml of water and has a mass of 59.5 grams. What is its density?
( quick search how could you determine what is it made of??)

• D = M/V  59.5g/ 7ml = 8.5 g/ ml
• D = M/V       7/ 59.5 = .117 ml/g
• D = M V =7 x 59.5 416.5 mlg

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
