An object will sink in a liquid if the density of the object is greater than that of the liquid. The mass of a sphere is 0.723 g. If the volume of this sphere is less than cm3, then the sphere will sink in liquid mercury (density

= 0.0532 cm^3

Explanation:

The computation of volume of the sphere is shown below:-

Where,

Density = 13.6 g/cm^3

Mass of sphere = 0.723 g

now we will put the values into the above formula to reach volume of the sphere which is here below:-

= 0.0532 cm^3

Therefore for computing the volume of the sphere we simply applied the above formula.
