  1. Density

  2. M V M D = D V Derived Units Volume = length  width  height Density = mass per unit volume (g/cm3 or g/ml)

  3. M D V Density An object has a volume of 825 cm3 and a density of 13.6 g/cm3. Find its mass. GIVEN: V = 825 cm3 D = 13.6 g/cm3 M = ? WORK: M = DV M = (13.6 g/cm3)(825cm3) M = 11,220 g

  4. WORK: V = M D V = 25 g 0.87 g/mL M D V Density (cont’d) A liquid has a density of 0.87 g/mL. What volume is occupied by 25 g of the liquid? GIVEN: D = 0.87 g/mL V = ? M = 25 g V = 28.7 mL

  5. WORK: D = M V D = 620 g 753 cm3 M D V Density(ugh… enough already) You have a sample with a mass of 620 g and a volume of 753 cm3. Find its density. GIVEN: M = 620 g V = 753 cm3 D = ? D = 0.82 g/cm3

  6. A gold-colored ring has a mass of 18.9 grams and a volume of 1.12 mL.Is the ring pure gold? (The density of gold is 19.3 g/mL.)

  7. What volume would a 0.871 gram sample of air occupy if the density of airis 1.29 g/L?

  8. A cup of sugar has a volume of 237 mL. What is the mass of the cup of sugar if the density is 1.59 g/mL?
