Question

A stone piece weighs 225g. By displacement method , its volume was found to be 75cm3 . What is the density of the stone piece.

Answer 1

Answer:

Here, mass of stone=225g =0.225kg =225/1000kg

volume of stone =75 cm3 =75/1000000 m3 .

Density =mass/volume = (225×1000000)/(1000×75)=3000kg/m^3 ans.

please follow me..

Answer 2

Mass = 225g

V = 75 cm^3

   = 225/75 = 3.0g/cm^3
