DENSITY

Density= Mass/Volume
Volume=Mass/Density
Mass= (Density)(Volume)



Some common units: g/cm3 for solids and g/mL for liquids

 





As you can see from the picture on the left, the rock's density caused the volume of the water to rise. The denser the solid dropped into the liquid, the higher the volume of the liquid will be.











A material will sink if its density is greater than the density of the liquid.
A material will float if its density is less than the density of the liquid.



Try these out for further practice:
1)A block of beeswax has a volume of 200.0 mL and a density of 961 g/L. What is the mass of the block?

2)A 70.0 g of manganese (density = 7.20 x 10^3 g/L) is dropped into a graduated cylinder containing 54.0 mL of water. What will be the water level indicated after the sphere is inserted?
