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 12.6 g. If the volume of this sphere is less than cm3, then the sphere will sink in liquid mercury (density = 13.6 g/cm3).

Volume of sphere = 0.93 cm³ (Approx)

Explanation:

Given:

Mass of sphere = 12.6 gram

Density of liquid mercury = 13.6 g/cm³

Find:

Volume of sphere = ?

Computation:

⇒ Density = Mass / Volume

⇒ Density of liquid mercury = Mass of sphere / Volume of sphere

⇒ 13.6 g/cm³ = 12.6 g / Volume of sphere

⇒ Volume of sphere = 12.6 / 13.6

⇒ Volume of sphere = 0.92647 cm³

⇒ Volume of sphere = 0.93 cm³ (Approx)

nah.   i'm just sleepy.
