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:
[tex]d=\frac{m}{V}[/tex]
Putting the values,
[tex]d=\frac{112 g}{10.7 mL}=10.46 g/mL[/tex]
The theoretical value of density of silver is [tex]10.5 g/cm^{3}[/tex] also, 1 mL is equal to [tex]1 cm^{3}[/tex] thus, density will be 10.5 g/mL.
This is approximately equal to the calculated value thus, the crown is made up of silver.
