Answer #1

1)

as it displaces 15 Kg of water

the volume is same as 15 Kg of water

volume of 15 Kg water = 15 Liter = 0.015 m^3

density of rock = 25/0.015

density of rock = 1667 Kg/m^3

the density of the rock is 1667 Kg/m^3

2)

as it displaces 15 Kg of gold

the volume is same as 15 Kg of gold

volume of 15 Kg gold = 15/19300 m^3

density of rock = 25/(15/19300)

density of rock = 32166 Kg/m^3

the density of the rock is 32166 Kg/m^3

3)

as it displaces 15 Kg of Mercury

the volume is same as 15 Kg of Mercury

volume of 15 Kg Mercury = 15/13600 m^3

density of rock = 25/(15/13600)

density of rock = 22666 Kg/m^3

the density of the rock is 22666 Kg/m^3
