The density of a material is 0.8 gm cm^-3. Express it in kg m^-3.

Open in App

Solution

Density of the object = 8 g/cm^3.
= (.8) (10^-3kg/10^-6m^3)
=.8 * 1000kg/m^3
=800kg/m^3
(1g=10^-3 Kg)(1cm=10^-2m)
(1cm^3=10^-6m^3)
The second step implies the conversion of one unit to another.Hope this answer will help you.
