Answer #1

1.

The weight of the object in air is

where p is the density of the object and V is the volume of the object.

The weight of the object in water is

F​​​​​​B is the buoyant force on the object in water, p​​​​​​w​​​​​ is the density of the water.

Dividing the two weights

2.

The density is approximately 2700 kg/m​​​​​​3​​​​​ which is the density of Aluminium. The chemical symbol is Al.
