The volume of water displace by crown is 10.7 mL. This will be equal to the volume of crown. Mass of crown is 112 g.
Density of a substance is defined as mass of substance per unit volume. It is mathematically represented as follows:
Putting the values,
The theoretical value of density of silver is also, 1 mL is equal to thus, density will be 10.5 g/mL.
This is approximately equal to the calculated value thus, the crown is made up of silver.
