3.4 Density More Calculations!

Definition Density is the ratio of the mass of an object to its volume. Density = mass/volume UNITS Mass  g Volume  cm3 or mL

Memory…

Example If an object has a mass of 5.4 grams and a volume of 6.23 mL, what is its density? Answer: 0.87 g/mL If an object has a density of 10.25 g/cm3 and a volume of 3cm3, what is its mass? Answer: 3 X 101g

DENSITY

More Complicated Problems An object with a volume of 15.2kL has the density of 2.564 g/mL. What is its mass? Answer: 3.90 X 107 grams An object that takes up 2659 dL of space and weighs 0.035 hectograms has what density (g/L)? Answer: 1.3 X 10-2 g/L
