How To Find Volume When You Have Mass And Density

Download Article

Density is the corporeality of mass an object has per unit volume (amount of space that object occupies).^[1] The metric units of density are grams per milliliter (1000/mL). Finding the density of water is relatively simple with the formula density = mass/volume.

1

Gather your materials. To calculate the density of h2o you will need a graduated cylinder, a calibration or balance, and water. Graduated cylinders are special containers that have lines or gradations that allow you to measure out a specific volume of liquid.
2
Weigh the empty graduated cylinder. In gild to find the density, you have to know the mass and volume of the liquid in question. You lot will apply the graduated cylinder to obtain the mass of the water, just you lot have to subtract out the weight of the graduated cylinder then you know yous're but measuring the mass of the h2o itself.
- Turn the balance on and brand sure it is set up to nada.
- Place the dry, empty graduated cylinder on the balance.
- Tape the mass of the cylinder in grams (k).
- For instance, let'southward say the empty graduated cylinder weighs 11 grams.

Fill up the graduated cylinder with water. Information technology doesn't matter how much water yous add, but be sure to note the verbal amount. Read the volume by looking at the cylinder at middle level and recording the book at the bottom of the meniscus. The meniscus is the curve of the liquid that you'll see when you await at the water right at center level.^[2]
- The volume of water in the graduated cylinder is the book you will use for the density calculation.
- Allow'due south say you filled the graduated cylinder with seven.3 milliliters (mL) of volume.
four
Counterbalance the water-filled graduated cylinder. Brand certain the balance is fix to zero and weigh the graduated cylinder total of water. Exist conscientious not to spill any of the h2o out of the top when you weigh it.
- If y'all do spill the h2o, take note of the new book and re-counterbalance the water-filled graduated cylinder.
- For example, let's say the full graduated cylinder weighs xviii.3 grams.
5
Subtract the weight of the empty cylinder from the full cylinder. To get the mass of the water only, you must subtract out the weight of the graduated cylinder. The consequence is the mass of the water in the cylinder.
- In our case, the mass of the graduated cylinder is eleven thousand and the mass of the cylinder full of water is 18.three g. 18.3 grand – 11 k = 7.3 grand, therefore the mass of the water is 7.iii grams.
6
Calculate the density by dividing the mass by the volume. Using the equation density = mass/volume, you tin can determine the density of water.^[three] Plug in the values of mass and book yous determined and solve.
- Mass of the h2o: vii.3 chiliad
- Volume of the water: 7.three mL
- Density of water = 7.iii/7.3 = i g/mL

1
Define the equation for density. Density is equal to the mass of an object, m, divided past the book, five, of that object. Density is represented with the Greek letter rho, ρ. An object that is denser volition have a greater mass for a smaller amount of book compared to an object that is less dense.
- The standard equation for density is ρ = yard/v.
2

Utilise the proper units for each variable. When calculating density, it is customary to employ metric units. The mass of an object is represented in grams. The volume of the object is in milliliters. You lot may also see book in centimeters cubed (cmⁱⁱⁱ).

Know why density is important. The density of an object tin be used to identify dissimilar materials.^[4] If y'all are trying to place a substance, you tin can calculate its density so compare it to the known density of other materials.
iv
Empathize factors that can influence the density of a water. Although the density of water is pretty close to 1 one thousand/mL, certain disciplines of science need to know the density of water with a higher specificity. The density of pure h2o is altered by temperature.^[5] Water density increases as the temperature gets colder.
- For example, at 0°C the density of water is 0.9998 g/mL, but at 80°C the density is 0.9718 m/mL. These differences may seem modest, but are very important to be aware of in scientific experiments and research.

Question

How does water ice accept less density than water?

About the freezing signal, water actually expands as information technology cools, making it less dense.
Question

How I can find the density of marbles in h2o?

Find the volume of the marbles (by water deportation), weigh the marbles, and divide their weight by their volume.
Question

How can I control the density of water?

You can add dissimilar solvents to change the density. For example, dissolving table salt will increment the density.
Question

How would my calculated density values be affected if I misread the book measurement on the graduated cylinder?

The volume measurement is existence divided by the mass, so the density would be different from what it really is supposed to be.
Question

Why is the density of the water the same every bit the volume?

Information technology isn't. Density is mass per volume, essentially the weight of the water that fills a given space. Information technology happens that in the metric system ane gram of water fills i milliliter of space, but that i-to-one relationship does not be in other measurement systems.
Question

Which is higher, petrol or oil?

The average motor (engine) oil is almost 30% denser than petrol/gasoline.
Question

How do I measure the density of a fish pond?

Follow the instructions higher up. Expect the density to be higher than it is with cleaner water.
Question

What principle was used?

Density is simply weight per volume. You lot collect a known volume of water and weigh it.
Question

How practise I calculate density relative to temperature?

Temperature does affect density to a small extent. In the case of water, it does expand if it freezes, and it will evaporate if information technology boils, in either case changing the density. All you can do is mensurate instantaneous book and weight at a given temperature. In the instance of humid water, measuring precise volume is difficult.
Question

How does the density of a liquid vary with the temperature?

Generally speaking, the density of a liquid (and most other matter) varies inversely with temperature.

If yous are using a glassware graduated cylinder, be careful not to break it. Glass is sharp when broken.

About This Article

Article Summary X

To find the density of water, counterbalance an empty graduated cylinder and record the mass of the cylinder in grams. Make full the graduated cylinder with h2o and record the exact amount at the bottom of the meniscus, or the curve formed by the surface of the water. Weigh the h2o-filled cylinder, then subtract the weight of the empty cylinder from the total cylinder. The consequence is the mass of the water in the cylinder. Divide the mass of the h2o past the volume, or the amount that was in the cylinder, to become the density. To acquire about the factors that can impact the density of water, like its temperature, proceed reading!
