Question

a substance has specific gravity 4. its density in SI is______​

Answer 1

Answer:

4000 kg/m^3

Explanation:

Specific gravity => relative density

And relative density= density of substance/density of water

d= 4 × density of water

d = 4× 1000 kg/m^3

d = density of substance = 4000kg/m^3

Answer 2

Answer: The density of the substance in SI units is 4000 kg/m³.

Explanation:

The specific gravity of a substance is defined as the ratio of the density of that substance to the density of water. Since water has a density of 1 g/cm³ in SI units, we can use this ratio to find the density of the substance in SI units.

Specific gravity = Density of substance / Density of water

4 = Density of substance / 1 g/cm³

Density of substance = 4 g/cm³

So the density of the substance in SI units is 4 g/cm³.

It is important to note that the SI unit of density is kilograms per cubic meter (kg/m³), which can be converted from the given value of density in grams per cubic centimeter (g/cm³) by multiplying by 1000. Therefore, the density of the substance in SI units is:

Density of substance = 4 g/cm³ x (1 kg/1000 g) x (1 cm/0.01 m)³ = 4000 kg/m³

Hence, the density of the substance in SI units is 4000 kg/m³.
