Calculate the volume of water, in milliliters, that would be displaced by a piece of gold weighing 18.2g.

The information needed for this question is the density of water. When we sum the forces acting on the system we would have:

Weight = Buoyant Force

mass of gold (g) = mass of H2O displaced (g)

mass of gold = density of water (Volume displaced)

Volume displaced = 18.2 g / 1000 g / L

Volume displaced = 0.0182 L or 18.2 mL
