Question

The density of iron is 7.97 g/cm. Express it in Sl unit.​

Answer 1

`d=7970\ kg/m^3`

Step-by-step explanation:

Given that,

The density of iron is 7.97 g/cm³.

We need to find the density in SI unit. The SI unit of density is kg/m³.

We know that,

1 kg = 1000 g

1 m = 100 cm

So,

`7.97\ g/cm^3=7.97 * (((1)/(1000))\ kg)/(((1)/(100)^3)\ m^3)\\\\=7970\ kg/m^3`

So, the density of the iron is
`7970\ kg/m^3`.
