In a laboratory, you determine that the density of a certain solid is 5.23×10−6kg/mm3. convert this density into kilograms per cubic meters.

The Density of a solid that is 5.23×10−6kg/mm3 is equivalent to 5230 kg/m^3  

Further Explanation Density is defined as the mass per unit volume of an object. Therefore density is given by mass of an object divide by its volume.  

That is; D = M/V

Density is measured in grams per cubic centimeter (g/cm³) For instance the density of water is 1 gram per cubic centimeter (1 g/cm³) However, density may be expressed in kilograms per cubic meter (kg/m³) For Example the density water may be expressed as 1000 kg/m³.  Other units of measuring density may be converted into SI units.

For example; In this case we are given density as 5.23 x 10^-6 kg/mm3

This density can be converted to kilograms per cubic meters as required;

1 x 10^9 mm^3 = 1 m^3

Therefore;

1 mm^3 = 1.0 x 10^-9 m^3  

Hence;  

5.23 x 10^-6 kg/mm^-3 = (5.23 x 10^-6 kg)/ 1 x10^-9 m^3  

                                    = 5230 kg/m^3  

Density depends on both mass and volume of an object. An object with high mass will have more density compared to an object with a lower mass. Therefore, density is directly proportional to mass and inversely proportional to the volume of the object.
