Question

Find the relative density of copper block of mass 216g having volume of 80cm3 (density of water= 1g/cm3)

Answer 1

relative density =density of object/ density of water
density =mass /volume
relative density =216/80/1
=216×1/80
=2.7




hope this cleared

Answer 2

Answer:

Density of block = Mass/volume = 216/80 = 2.7 g/cm3

Relative density = Density of a substance / Density of water = 2.7/1 = 2.7
