Answer 1

Explanation:

density =mass/volume

so densit =8/3cm³

Answer 2

Relative density of coal = 4/3

Explanation:

We know that,

Density = Mass/Volume

and

Relative density = Density of substance / Density of water

Given that,

Mass = 40g

Volume = 30cm³

Density of water = 1 g/cm³

Hence,

Density = Mass / Volume

Density = 40/30

Density = 4/3 g/cm³

Hence,

Relative density of coal = Density of coal / Density of water

Relative density of coal = ( 4/3 ) / (1)

Relative density of coal = 4/3
