Question

The density of alcohol is 800 $Kg/m^3$. Its relative density is:

• A. 8
• B. 0.8
• C. 0.08
• D. 800

Answer 1

Answer: (B)

0.8

Relative density is the ratio of the density of the substance to the density of water.

We know that, density of water is $1gm/c{m}^3={10}^{3}kg/m^3$

So, relative density of alcohol = $\frac{800}{1000}$ = $0.8$

Hence, option B is correct.
