What is the Formula for Density

What is the Formula for Density Density is a physical property of a substance and it is the measure of the amount of mass in a given standard measure of volume. Density is a unique property and hence it is different for different substances. Therefore density is given as mass per unit volume and its formula is written as: density, d = (mass) / (volume). The unit of density depends on the unit of mass and unit of volume, and while measuring the standard density of a substance, density is usually calculated with respect to standard volume. Example 1: An object has a mass of 40grams. If the object has a volume of 6cm3, then what is the density of the object? Given: mass of the object, m = 40g Volume of the object, V = 6cm3 Density, d = (mass) / (volume) Now we apply the above formula to the given information of the question. This implies, density of the given object, d = (40g)/ (6cm3) This gives, density, d = 6.67g/cm3 Therefore, density of the given object is 6.67g/cm3 Example 2: A liquid in a beaker has a mass of 25grams. If the liquid occupies avolume of 100mL, then what is the density of the liquid? Given: mass of the liquid, m = 25g Volume of the liquid, V =100mL Density, d = (mass) / (volume) Now we apply the above formula to the given information of the question. This implies, density of the given liquid, d = (25g)/ (100mL) This gives, density, d = 0.25g/mL Therefore, density of the given liquid is 0.25g/mL
