Dylan has two beakers filled with liquids. Beaker A has a liquid with a density of 1.78 grams/mL and Beaker B has a liquid with a density of .64 grams/mL. If Dylan poured the beakers into a graduated cylinder, what would happen?

• The liquid in Beaker A would float on the liquid of Beaker.

• The liquid in Beaker B would float on the liquid of Beaker A.

• The liquids would turn into a solid.

• The liquids would combust.

What is the formula for the density of an object?

• D = Mass x Volume

• D = Volume / Mass

• D = Mass + Volume

• D = Mass / Volume
