Here are the three equations to use:
- Mass = Density x Volume
- Density = Mass ÷ Volume
- Volume = Mass ÷ Density
- Look up the density of the material the object is made of in kg/m³.
- Measure the volume of the object in m³.
- Multiply the density by the volume.
- You will then have the mass of the object in kg.
What is the equation for mass density and volume?
p = m V Where: p = density m = mass V = volume The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
What is the relationship between density and volume?
Volume is the three-dimensional space enclosed by the closed surface. Density is mass per unit volume. The relation between density and volume is directly proportional. That is any change in volume will result in the change in its density and vise-versa. The density and volume are proportional to each other and can be mathematically expressed as-

How do you find the mass when given the density?
Remember, you can arrange one formula to solve for mass, density, or volume. Here are the three equations to use: Mass = Density x Volume. Density = Mass ÷ Volume.
How do you calculate the mass?
One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.
How do you find mass using volume?
Volume equals mass divided by density; and. Mass equals density times volume.
What is mass and volume?
Mass is the physical quantity that signifies the amount of the matter in the body of an object. Volume is the evaluation of how much 3-multidimensional space is occupied by the object. Mass is the physical value.
How do you calculate mass with volume without density?
0:175:17How to find density, mass, and volume - YouTubeYouTubeStart of suggested clipEnd of suggested clipAnd this is density. So if you need density its mass over volume if you need volume its mass dividedMoreAnd this is density. So if you need density its mass over volume if you need volume its mass divided by density.
How do you find the mass if you have the volume and density of water?
Example Problemmass = volume x density.mass = 30 ml x 0.790 g/ml.mass = 23.7 g.
How do you find the mass of a liquid?
Mass the fluid, find its volume, and divide mass by volume. To mass the fluid, weigh it in a container, pour it out, weigh the empty container, and subtract the mass of the empty container from the full container. To find the volume of the fluid, you simply measure it very carefully in a graduated cylinder.
Formula
The formula used by this calculator to determine volume from mass and density is:
Mass Measured
Enter the measured mass of the object and select the appropriate mass measuring units.
Volume Calculation
This is the volume of the substance, which can be converted into any volumetric units.
How to find mass and volume?
Remember, you can arrange one formula to solve for mass, density, or volume. Here are the three equations to use: 1 Mass = Density x Volume 2 Density = Mass ÷ Volume 3 Volume = Mass ÷ Density
What is density in math?
Density is the amount of matter, or mass, per unit volume. This example problem shows how to calculate the mass of an object from a known density and volume.
Calculating density
The density of a material is scientifically defined as its mass per volume. It can also be thought of as how compacted or compressed a substance is. When calculating a density from a mass and volume figure, it's important to remember that density can be affected by pressure and temperature, particularly where gases are concerned.
Calculating mass from density and volume
To calculate mass, simply rearrange the structure of the overall density formula. Multiply your density figure by your volume figure: m = ρ x V
Calculating volume from mass and density
To calculate volume, rearrange the structure of the density formula in order to divide your mass figure by your density figure : V = m / ρ
How to find volume of a solid?
Finding Volume by Displacement. If you're given a regular solid object, you can measure its dimensions and calculate its volume. Unfortunately, the volume of few objects in the real world can be measured this easily! Sometimes you need to calculate volume by displacement.
What is the density of matter?
Density is how much matter is contained within a volume. A dense object weighs more than a less dense object that is the same size. An object less dense than water will float on it; one with greater density will sink. The density equation is density equals mass per unit volume or D = M / V. The key to solving for density is to report ...
Can you measure volume with a graduated cylinder?
The same goes for measuring volume. Obviously, you'll get a more precise measurement using a graduated cylinder than using a beaker, however, you may not need such a close measurement. The significant figures reported in the density calculation are those of your least precise measurement.
Is 22 kg a high density?
Another important concept to keep in mind is whether your answer makes sense. If an object seems heavy for its size, it should have a high density value.
How to Find Volume using Mass Density Vocabulary
Density: Density is the amount of mass per unit volume. and is given by the formula: $$\text {density} = \frac {\text {mass}} {\text {volume}} $$
How to Find Volume using Mass Density: Example 1
Calculate the mass of an unknown sample with a mass density of {eq}3 \text {kg/m}^3 {/eq} and a mass of {eq}9 \text {kg} {/eq}.
How to Find Volume using Mass Density: Example 2
Calculate the mass of an unknown sample with a mass density of {eq}1.2 \text {kg/m}^3 {/eq} and a mass of {eq}6 \text {kg} {/eq}.
Simple Example
Problem
Solution
- Density is equal to the mass divided by the volume. D = m/V where D = density m = mass V = volume We have the density and enough information to find the volume in the problem. All that remains is to find the mass. Multiply both sides of this equation by the volume, V and get: m = DV Now we need to find the volume of the gold bar. The density we have been given is in grams per …
