water?
a. their densities are equal
b. oil has a greater density than
water
c. water has a greater density than
oil
d. oil and water must have equal
masses and volumes

B

Explanation:

Water molecules are made up of oxygen and hydrogen atoms bonded together. Oxygen is heavier and smaller than carbon, so a volume of water molecules is heavier than the same volume of oil molecules. This makes water more dense than oil.
