A243 ml cup of whole milk contains about 45 mg of cholesterol. express the cholesterol concentration of the milk in kilograms per cubic meter (kg/m^3).

The cholesterol concentration of the milk in kilograms per cubic meter is 0.1851 kg/m³

The calculation is done as follows;

1 mg= 10⁻⁶ kg

1ml= 10⁻⁶ m³

= 45 ÷243

= 0.1851 kg/m³

Hence the cholesterol concentration of the milk is 0.1851 kg/m³
