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**.
