Question

The relative density of a metal alloy is 5.6 Its density in SI units will be​

Answer 1

Pascal
As that’s the SI unit of density

Answer 2

Answer:

The density in SI units will be 5.6 x 10³ kg/m³

Explanation:

We know that the relative density  = density of mercury / density of water

So, 5.6 = density of mercury / 1gcm⁻³

or, density of mercury = 5.6gcm⁻³

The relevant density is in CGS unit

FOR SI UNIT,

Density in SI unit = $\frac{5.6 * 100*100*100}{1000}$ kg/m³

or, Density in SI unit = 5.6 x 10³ kg/m³

Relative Density : It is defined as the ratio of the given density of any substance to the standard density of water, gas or air.

Its CGS unit is gcm⁻³ and its SI unit is kg/m³.
