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 the butt uses of density and the density formula. Hi there are we at school this afternoon and if so what time should you head to school defenc is the day you want me to go to the get one ☝️

## Using the Formula[edit]

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 property[edit]

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 Questions[edit]

**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 Reading[edit]

- 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 Thinking[edit]

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