Question

A hollow metal of mass 180.6g contains cavity of volume 2.5cm³. This metal when placed in water displaces 25cm³ of water. Find specific gravity of metal.

Open in App

Solution

Specific gravity is the ratio of density of object to the density of water
now,
density of obj=Mass/vol
=180.6/2.5
so specific gravity =
180.6/(2.5×250)
=0.288
