Determining Density Chapter 2 Section 2 pp

DENSITY Is a property of matter. Can be measured in either g/mL, g/cm 3 or kg/m 3. is usually measured in g/mL (for liquids) or g/cm 3 (for solids).

DENSITY 1 g/cm 3 = 1000 kg/m 3 To convert from g/cm 3 ---> kg/m 3, multiply by i.e g/cm 3 = 920 kg/m 3 To convert from kg/m 3 ---> g/cm 3, divide by 1000.

DENSITY The density of a material is the same no matter what the size or the shape of the material. Liquids tend to be less dense than solids of the same material Water is an exception.

Density Formula used to calculate density D = m V Where D = density (measured in g/cm 3 ) m = mass (measured in g) And V= volume (measured in cm 3 )

DENSITY Density tells how tightly packed the atoms or molecules of a material are. The density if a hollow object is less than the average density of the material the object is made of.
