Question

Find the relative density of a metal whose density is 4200 kgm-3​

Answer 1

Answer:

4.2

Explanation:

relative density is density of substance divided by density of water i.e. 1000kgm-3

therefore relative density = 4200÷ 1000

i.e. 4.2

Answer 2

Answer:

4.2

Explanation:

Relative density = Mass of vol. of substance/ Mass of vol. of water

we know density = mass * volume

mass of volume of water (i.e. density) = 1000 kg m-3

therefore RD of metal = 4200/ 1000

                                    = 4.2
