Calculating Density Notes

To find the density of a material, you need to know the mass and the volume of the material.
The Formula to find density is:
D = M/V
(Density = Mass ÷ Volume)
Example:
Find the density of a material that has a mass of 34 grams and a volume of 16 ml
Step one: Write out the equation for density
D= M ÷ V
Step two: Plug in known information
D= 34 g ÷ 16 ml
Step three: Calculate
D = 2.125 g/ml

• The density of water is 1 g/ml

o Any material that has a density ABOVE 1 g/ml will sink.
o Any material that has a density BELOW 1g/ml will float.
