Density of milk is 1.03 g/cm 3 and density of water is 1 g/cm 3.
| Density of milk is 1.03 g/cm3 and density of water is 1 g/cm3. Find the relative density of milk.
A. 1.03
B. 0.103
C. 0.0103
D. 0.00103
Please scroll down to see the correct answer and solution guide.
Right Answer is: A
SOLUTION
Relative density of a body is defined as the ratio between the densities of the body to the density of water at 4°C (1 g/cm3or 1000 kg/m3).
\(Relative\:density = \frac{{Density\:of\:milk}}{{Density\:of\:water}} = \frac{{1.03}}{1} = 1.03\)
Unit: Since the relative density is a ratio of two densities, it has no unit.
