density is defined as its mass per unit volume In other words density is the ratio of mass to volume or mass per unit volume It is a measure of the amount of things an object has in a unit of volume cubic meter or cubic centimeter Density is essentially a measure of how tight the matter is the principle of density was discovered by the Greek scientist Archimedes and it is easy to calculate if you know the formula and understand its related units
Formula To calculate the density (ρ) of an object, take the mass (m) and divide by the volume (v): ρ = m / v The SI unit of density is kilogram per cubic meter (kg/m3). It is also frequently represented in the cgs unit of grams per cubic centimeter (g/cm3). Calculate Density When studying density it can be helpful to solve a sample problem using the formula for density as mentioned in the previous paragraph. Remember that although density is mass divided by volume it is often measured in units of grams per cubic centimeter because grams represent a standard weight while cubic centimeters represent the volume of the object .Here is the simple method for calculating the Density and mass/volume through MeraCalculator. For this problem, take a brick of salt measuring 20.0 cm x 10.0 cm x 2.0 cm, which weighs 600 grams. To find the density, use the formula, which helps you determine the amount of mass per unit volume. ρ = m / v In this example, you have the dimensions of the object, so you have to calculate the volume. The formula for volume depends on the shape of the object. v = length x width x thickness v = 20.0 cm x 10.0 cm x 2.0 cm v = 400.0 cm3 Now that you have the mass and volume, calculate the density, as follows: ρ = m / v ρ = 600 g/400.0 cm3 ρ = 1.5 g/cm3 Thus, the density of the salt brick is 1.5 g/ cm3.
