A) The mass of sand removed divided by the volume of the original plastic bottle equals the density of the ocean water.
B) The mass of the sand removed divided by the mass of the sand remaining in the plastic bottle is the same ratio as the density of fresh water to the density of ocean water.
C) The amount of sand removed from the plastic bottle equals the amount of salt dissolved in the ocean water.
