Question

The density of water is 1000 kg m-3. if relative density of iron is 7.874 , then calculate the density of iron .

Answer 1

rel. density = density of object/ density of water

density of obj. = rel. density * density of water

density of iron = 7.874 * 1000 $kg m^{-3}$

                        = 7874 $kg m^{-3}$

Answer 2

Answer:7.874

Explanation:R.D=(density of substance )÷(density of water)____1

R.D=7.874

Density of water is 1000kgm3

Subs this values in 1 eq

7.874=(density of substance )÷1000kgm3

Density of substance =7.874×1000

Density of substance =7874
