Buoyant force = (Water density) x (gold volume)x g

The volume of the gold is

(mass)/(gold density)= 3.11*10^-5 m^3

The density of water is 1000 kg/m^3

The answer will be in Newtons after multiplying by g.

This is obviously not a tooth crown - At 0.6 kg, it would weigh 19 oz. and cost %26,000 at today's prices
