Question

Calculate the mass of a body whose volume is 2 m^3 and relative density is 0.52.

Answer 1

Heya user ,
Here is your answer !!

We know that , Density ( D ) = Mass ( M ) / Volume ( V ) .

=> M = D × V .

Given , V = 2 m³
and , R.D. = 0.52
so , density = 0.52 * 1000 kg/m³ = 520 kg/m³

So , mass ( M ) = 2 m³× 520 kg/m³ = 1040 kg .

Hope it helps !!

Answer 2

Volume of the body = 2 m^3

Relative density, RD = 0.52

Mass of body = Density × volume.
We know volume and relative density. We need to find density first.

Density of body = RD × density of water

=> density = 0.52 × 1000 = 520 kg/m^3


Now, mass of body = density × volume

=> Mass = 520 × 2 = 1040 kg


Hence mass of body is 1040 kg.
