A 6.2kg piece of metal displaces 0.80 L of water when submerged.Find its density.

Answer 1

The metal will displace water equal to its volume, since it will sink.

You surely know the formula for density: (mass/(volume)

Use it.

Density can be in kg/liter or g/cm^3. The number will be the same, since 1000 g = 1 kg and 1000 cm^3 = 1 liter
