Question

First question define the relative density second question find the relative density of Mercury if density 13.6 into 10 raise to the power 3 kg per metre cube

Answer 1

Relative density is the ratio of body to the ratio of water at 4 degree celcius.

density of mercury in kg per metre cube =13×10 raised to the power 3

that is 13 gram per cm cube

relative density can also be defined as the density of body in g per cm cube
therefore,relative density of mercury=13.6
