Question

A piece of iron weighs 275g; the piece floats with 5/9th of its volume immersed in mercury whose density is 13.6g/cm^3.Find the volume and density of the piece of iron

Answer 1

Density of body = fraction of body in liquid x density of water

=( 1 — 1/3) x 1 = 2/3

Density of liquid = density of body / fraction of body in liquid

= 2 / 3 ÷ 1 / 4

= 2 x4 / 3 x 1

= 8 / 3

= 2.67
