What is Density Formula?

What is density formula? Well, that is a question so popular to people new to the concepts of mass, weight and volume of matter. To start off we must first establish what matter really is and what it is not. Now matter, simply put, is anything that occupies space and has mass. This is to mean that matter must be contained somewhere if it exists. It should also have another component called mass. Let us explore this further. Read more great facts, click here

The mass of any object is the quantity of that object which expresses the amount of matter. Mass is measured in kilograms. For instance, if we wanted to know the amount of maize flour in a sack, we would put that sack on a weighing balance. Whatever we found, say 90 kilograms, that is the mass of that flour, or the amount of flour in that sack. Very simple, right? For more useful reference , have a peek here

Matter will also occupy space. Now space is what will scientifically be referred to as the volume of matter. Assuming, the 90 kilograms bag of flour occupies one cubic meter of space, expressed as 1m3. The volume of the 90 kilograms bag of maize flour is thus one cubic meter. 

Now the amount of space matter occupies is determined by how heavy that object is. The heaviness of an object is what density is. Density formula therefore is a mathematical expression showing the relationship between the volume and the mass of an object. The evaluation of the ratio of the mass to the volume of the object is what gives us the density formula. When we talk of a ratio, it is a simple division mathematics. Thus far we have seen that the formula for density of any object is the ratio of its mass to its volume.  Mathematically stated it is the mass of an object divided by its volume. Taking our example of the ninety kilograms sack of maize flour, its density will be obtained from the formula as follows:

Mass of the maize flour is 90 kilograms and the volume it occupies is one cubic meter. Since density is equals to mass divided by volume, then the density of the flour is simply 90kg/1m3. The result is 90kg/m3. This means that a 90 kilograms sack of maize flour will always occupy that amount of space anywhere in the face of the earth. This is just a hypothetical example. Flour could be lighter or heavier than what we have calculated. Standard densities for different objects are available on many reliable scientific publications and can be obtained on demand.
