# DensityEdit

Density is possibly one of the most useful properties when studying matter. Each substance has a unique density. Density is determined by using the "density formula". The density formula is as follows: D=M/V or **Density** equals **Mass** over (divided by) **Volume**. Density is the amount of **matter** that can be placed in one cm^{3} of space. The following section discusses the uses of density and the density formula.

## Using the FormulaEdit

The **variables** of the **density** formula can be rearranged to solve the equation for different measurements. The **density** formula is capable of solving for **Mass** when **Density** and **Volume** are known, **Volume** when **Density**, and **Mass** are known, and **Density** when **Mass** and **Volume** are known.

- D=M/V (
**Density**equals**Mass**over**Volume**) - M=VxD (
**Mass**equals**Volume**times**Density**) - V=M/D (
**Volume**equals**Mass**over**Density**)

## As a propertyEdit

All substances have different **densities** although two densities may be similar and even undetectably different by some instruments, all densities are different because in each substance, the **atoms** are packed together in a different way. Solids are the most dense, because their atoms are packed closest together. Liquids are less dense then solids, and gasses are the least dense.

# Vocabulary and QuestionsEdit

**Density**is a measurement of the amount of a substance that can fit into one cubic centimeter of space**Density Formula**D=M/V: Density equals mass over volume**Variables**are placeholders in an equation that represent a number that is not yet known

## Covering the ReadingEdit

- If copper has a density of 8.96 g/cm
^{3}how much mass would a piece with a volume of 34cm^{3}have? - If a material has a mass of 52.457 g and a volume of 13.5cm
^{3}, then what is the density of the material?

## Critical ThinkingEdit

- Are there any other variables that the density formula can be rearranged to solve? why or why not?
