Objects that sink in water have a density higher than 10 g per cubic centimetre. Mathematical formulas are used to calculate optical density also known as absorbance. The probability density function PDF of a random variable X allows you to calculate the probability of an event as follows.
Density Formula Density is a measure of relative compactness or how heavy an object is relative to its size.
Normally in math density is a mass or number per unit volume. Density Formula Density is a measure of relative compactness or how heavy an object is relative to its size. The density calculator uses the density formula. Density is the measurement of the amount of mass per unit of volume.
