Answer 2

Answer:

The relative density of the block is equal to 2.

Explanation:

Relative density of a substance is the ratio of density of substance to the density of water. Relative density have no units.

Given, the Volume of the block = 400cm³

The mass of the block = 800g

The density of the block can be calculated by dividing the mass of the block by its volume.

Density of the block $=\frac{800g}{400cm^3}$

Density of the block = 2 g/cm³

Relative density can be calculated by dividing the density of the block with density of water.

The density of water = 1 g/cm³

Relative density = density of block/ density of water

Relative density of block $=\frac{2 \;g/cm^3}{1 \;g/cm^3}$ = 2

Therefore, the relative density of the block is equal to 2.
