  1. You have a sample with a mass of 700 g and
    a volume of . Find its density.
  2. When the BP Oil Spill occurred in 2010 , oil could be seen floating on the surface of the Gulf of
    Mexico for miles. If the oil has a density equal to , then what must be true about the density

Answer

Problem 24

Given:
  • Mass = 700 g
  • Volume = 524 cm³
Density Calculation:
Answer:
The sample’s density is approximately 1.336 g/cm³.

Problem 25

Given:
  • Oil density = 0.84 g/mL
Observation:
  • Oil floats on water.
Conclusion:
Answer:
Water in the Gulf must be denser than 0.84 g/mL for oil to float on it.

To find the density of your sample, you simply use the formula . Plugging in your numbers, . This tells you how compact the mass is within a given volume—pretty cool, right?
In terms of the BP Oil Spill, since the oil has a density of , which is less than the density of water (approximately , or ), it means the oil will float on the surface of the water. That’s why, despite its environmental disaster implications, the visible oil slick formed on top of the ocean water for miles!
