# Density

## Objective

Use the density formula to solve for density, volume, or mass of a substance given the other two quantities.

## Density Formula

Sometimes you may only have two known values, and you will need to solve for the unknown value. This will make you manipulate the equation to your convenience.

## Density

When density (D) is the unknown quantity, you will plug in the volume (V) and mass (M) into the equation and solve. The solution to the equation will be the density (D).

## Mass

When mass (M) is the unknown quantity, you will first manipulate the density formula to solve for the mass (M). Once you have manipulated the equation, you will plug in the volume (V) and density (D) into the equation to find the mass (M).

To manipulate the equation follow the following steps:

## Volume

When volume (V) is the unknown quantity, you will first manipulate the density formula to solve for the volume (V). Once you have manipulated the equation, you will plug in the mass (M) and density (D) into the equation to find the volume (V).

To manipulate the equation follow the following steps:
