Question

the mass of 5 litre of water is 5kg. find the density of water

Answer 1

Your Answer :

Mass = 5 kg

Volume = 5 Litres

Volume in m³ = 5 × 10-³ m³

Density = Mass / Volume

Density = 5 / 5 × 10-³ = 1000kg/m³

Answer 2

Given is the mass of water = 5 kg

Also, the volume of water is given as 5 litres, on converting volume into ${ m }^{ 3 }$

We get,

                     $5\times 10^{ -3 }m$

We know the formula for density is mass per unit volume.

So,

                     $D=5kg/5\times 10^{ -3 }m^{ 3 }$

This gives us the value of density with its unit as $1/10^{-3} kg/m^3\quad or\quad 1000 kg/m^{ 3 }$.
