The density of a metal is $10.8$ x $10^{3}$ kg/ $m^{3}$ . Find the relative density of the metal. (Density of water is $10^{3} K g / m^{3}$ )

Open in App

Solution

Relative density $= \frac{d e n s i t y o f g i v e n s u b s t a n c e}{D e n s i t y o f s t a n d a r d s u b s t a n c e (w a t e r)}$
Relative density $= \frac{10.8 \times 10^{3}}{10^{3} (d e n s i t y o f w a t e r)} = 10.8$
