The relative density of pure gold is 19.3. When an ornament made of gold is immersed completely in water, the volume of the water displaced is 5 ml. If the mass of the ornament in air is 100 g, determine whether the ornament is made of pure gold.

Answer»

Solution :(i) DENSITY `=(m)/(v)`
density `=("MASS")/("VOLUME of liquid displaced")`
If the ornament is made of pure GOLD, the density of the ornament MUST be equal to the density of gold.
(ii) `20 g cm^(-3)`
