# How To Work Out Density?

## What are two ways to calculate density?

Using a vernier caliper or ruler, measure the length, depth and width of the object in centimeters.

Multiply these three measurements to find the volume in cubic centimeters.

Divide the object’s mass by its volume to determine its density.

Density is expressed in grams per cubic centimeter or grams per milliliter.

## What are the 3 equations for density?

What are the three formulas for density?

• To work out density: p = m / V.
• To work out the mass: m = p x V.
• To work out the volume: V = m / p.

## How do you find average density?

In order to find the density, I simply divided the mass found by the volume found. For example, 30.0035 g divided by 30.425 mL equals 0.9861 g/mL. To find the average density, I added the three densities I found, then divided that total by three to find the average.

## How do you convert density to grams?

In order to convert density to grams, you have to put the mass on one side of the equation, and the density and the volume on the other. Therefore, d * v = m. Multiply the density by the volume. Using the example in step 1, you would multiply 2 g/mL by 4mL.

## How do you convert density units?

Density unit conversions –

## How do you convert density to weight?

Density is useful in calculating the weight of substances that are difficult to weight. You can determine its weight simply by multiplying the density by the size, or volume, of the item. Write down the volume and the density of the item you’re measuring.

## What is the formula for area?

The most basic area formula is the formula for the area of a rectangle. Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width.

## How do you find volume?

Units of Measure

1. Volume = length x width x height.
2. You only need to know one side to figure out the volume of a cube.
3. The units of measure for volume are cubic units.
4. Volume is in three-dimensions.
5. You can multiply the sides in any order.
6. Which side you call length, width, or height doesn’t matter.
