A piece of aluminum has density 2.70 g/cm³ and mass 834g.The aluminum is submerged in a container of oil (oil's density = 0.650 g/cm³).How much oil does the metal displace?

Question

Quizplus · Accepted Answer

The volume of the aluminum can be found by dividing its mass by its density:
Volume of aluminum = 834g ÷ 2.70 g/cm³ = 309 cm³
According to Archimedes' principle, the volume of fluid displaced by a submerged object is equal to the volume of the object. Therefore, the aluminum displaces 309 cm³ of oil. Answer choice B is correct.
