Question

Relative density $=\frac{\text{density of substance}}{X}$ where '$X$' is:

• A. Density of substance
• B. Density of water
• C. Density of bottle
• D. Density of gas

Answer 1

The correct option is B Density of water

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

Thus, relative density $=\frac{\text{density of substance}}{\text{density of water}}$

Hence, $X=$ density of water
