When we’re talking about density the formula you need to know is mass / volume = density. This formula is expressed in grams per cubic centimeter (g/cm3). Calculating density is an important concept in science and will help you if you find a career in that field. It’s useful for a wide variety of things like determining they type and identity of rocks and minerals. Once you know the density of an object it is easier to determine what that object could be, or how that object will effect your experiment.
When it comes to density you get an obvious feel for how dense or not an object might be. Objects that have a loose or airy appearance are less dense compared to something that is hardened and smooth like iron or some of the denser metals. Of course, there are a few things you need to be aware of, and one or those is mass. These two terms are not interchangeable. When people describe mass they use the phrases heavy and/or light, whereas density can not. Having an object with a high mass and low density is common. When you are talking about density you also have to know the size, or volume, of an object for determining the final value. Here’s a good read about density, check it outhttps://www.okcalculator.com/density-mass-calculator.html.
When measuring the density of an object you aren’t weighing the object directly. You need to weigh the object and measure it’s volume so you can get an accurate number. You can’t add densities when you’re determining the density of an item with more than one element. When determining the density of a table made from two different types of rock, one at 3g/cm3 and the other at 4g/cm3 then you have to say the table is between 3 and 4g/cm3. Every type of object has an average density. Objects like gas which have a density in the thousandths of grams per cubic centimeter. Liquids have a density of around 1 g/cm3. The heavier objects like rocks and metals have an average of about 3 and 6, respectively.

Density is an important thing to know because it helps when it comes to other calculations like specific gravity, which is the comparison of an objects density to that of water, which is 1 g/cm3. Specific gravity is used a lot in the medical field when it comes to instrumentation and urinalysis readings. Knowing the density of an object is critical in many other areas of science. Knowing the density of an object you can determine if one will float or not. Less dense substances will obviously float and more dense substances will sink, like the Titanic. Density can help explain a lot of things, like why a helium balloon floats and why the water at the bottom of the pool is colder.
