Which has a higher density, a liquid with a mass of 100g and a volume of 50mL, or a liquid with a mass of 200g and a volume of 100mL?

• The liquid with a mass of 100g and a volume of 50mL has a lower density.

• Equal densities

• The liquid with a mass of 200g and a volume of 100mL has a higher density.

• The liquid with a mass of 100g and a volume of 50mL has a higher density.

If the mass of a liquid is 500g and its volume is 250mL, what is its density?

• 3g/mL

• 1g/mL

• 2g/mL

• 0.5g/mL

Why does oil float on water?

• Oil floats on water because it is heavier than water.

• Oil floats on water because it is less dense than water.

• Oil floats on water because it evaporates quickly.

• Oil floats on water because it is attracted to water.
