Question

the mass of an empty density bottle is 30g,it is 75g when filled completely with water and 65g when filled completely with a liquid.find:-
(a) volume of density bottle,
(b) density of liquid,and
(c) relative density of liquid

Answer 1

Density in kg/m^3 = (Relative Density)*(Relative density)

We know density of water = 1000 kg/m^3

Substituting values of relative density and density of water in the above equation for Density, we get:

Relative density of liquid = 0.8*1000 = 800 kg/m^3
