# Mass formula with volume and density relationship

### How To Convert Volume To Weight To extend the concepts of proportional relationships to intensive properties of substances. relationship between mass and volume of the substance. Density. Density is defined as mass per unit volume. Data can be entered into any of the boxes below. Specifying any two of the quantities determines the third. Density is a way of comparing how heavy different materials are. The formula for density can be rearranged to calculate the mass or volume of an object.

For liquids and gases, the sample substances are put into a container and calculated. Volume is expressed in units and subunits like cubic meters for solids and cubic liters for liquids and gases. Density and volume have an inverse relationship with each other. If density increases, the effect will be a decrease in volume.

In contrast, if the volume increases, density decreases. Both density and volume are physical properties of matter. They are present in the traditional stages of matter, which are solid, liquid, and gas. Both density and volume have a specific formula regarding solids or regular-shaped objects. In measuring liquids and gases, there is a little deviation from the traditional approach or formula.

### The Relationship Between Mass, Volume & Density | Sciencing

Density measures the amount of matter present in an object. Meanwhile, volume is concerned with the amount of space that an object occupies. The density formula for solid or three-dimensional objects comprises two components — mass and volume. In this view, volume is a component of density. On the other hand, the volume of a regular shape is determined by three dimensions: In many instances, volume is measured by the use of a graduated cylinder, water, and a specific object.

In terms of units, density units are a composite and involve the mass and volume components. In contrast, there is only one component involved in the volume, which is the unit used for volume only. Density and volume have inverse relationships in accordance with the mathematical formula for density.

When students plot their data, there should be a straight line showing that as volume increases, mass increases by the same amount.

### How are density mass and volume related? + Example

Discuss student observations, data, and graphs. Use your graph to find the mass of 40 mL of water. What is the density of this volume of water? The mass of 40 mL of water is 40 grams. Choose a volume between 1 and mL. Use your graph to find the mass. Tell students that density is a characteristic property of a substance. This means that the density of a substance is the same regardless of the size of the sample. Is density a characteristic property of water?

How do you know? Density is a characteristic property of water because the density of any sample of water at the same temperature is always the same. Explore Project the image Density of Water. Water molecules all have the same mass and size.

## Difference Between Density and Volume

Water molecules are also packed pretty close together. They are packed the same way throughout an entire sample of water. So, if a volume of water has a certain mass, twice the volume will have twice the mass, three times the volume has three times the mass, etc. No matter what size sample of water you measure, the relationship between the mass and volume will always be the same.

Project the animation Liquid Water. Water molecules are always moving. But on the average they are packed the same throughout.
