Density Notes

What is density? How much mass is in a volume How much matter is in a given space How compact particles are in a space Which is more dense?

= density- amount of matter is in a given space SI: kg/m 3 g/mL g/cm 3 mass- amount of matter in a substance SI: gram volume- amount of space a substance takes up SI: liter cm 3 m 3

Density Formula Density = mass/volume Mass = ? Volume = ?

The Magic Triangle

Let’s Practice… 1.What is the density of a rock with a volume of 6 mL and a mass of 24 g? 2.A block of wood 3 cm on each side has a mass of 27 g. What is the density of the block? 3.Silver has a density of 10.5 grams/cm 3 and gold has a density of 19.3 g/cm 3. Which would have the greater mass, 5cm 3 of silver or 5cm 3 of gold? 4.What is the volume of a block that is 12 grams with a density of 4 g/mL? 5.What is the mass of an unknown substance that is 4 mL and 8 g/mL?
