A king ordered a goldsmith to prepare a crown wth 1 kg pure gold. The relative density of pure gold is given as 19. Is it possible to find the adulteration if the goldsmtih adds some impurity inmaking the crown. If so how? Explain.

Answer» SOLUTION :The mass of the crown can be measured by using a BALANCE that can measure the mass more accurately. The volume of the crown can be found by immmersing it in an overflow jar and measuring the volume of water over flown. Once the mass of the crown and its volume are known, its DENSITY of the crown is 19 g cm^(-3) (Since relative density of gold is given as 19) , the crown is made of pure gold. OTHERWISE it can be concluded that the crown is made adulterated gold.
