how to calculate density of water

by Dr. Porter Hayes Published 2 years ago Updated 1 year ago

  1. Gather your materials. To calculate the density of water you will need a graduated cylinder, a scale or balance, and water.
  2. Weigh the empty graduated cylinder. In order to find the density, you have to know the mass and volume of the liquid in question.
  3. Fill the graduated cylinder with water. It doesn’t matter how much water you add, but be sure to note the exact amount.
  4. Weigh the water-filled graduated cylinder. Make sure the balance is set to zero and weigh the graduated cylinder full of water.
  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.
  6. Calculate the density by dividing the mass by the volume. Using the equation density = mass/volume, you can determine the density of water.

The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid. Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume; D = m/v. The density of water is 1 gram per cubic centimeter.

How much density is 1g/1cm3?

So, 1g/1cm 3 = 1 g/cm 3 , giving water its easy-to-remember density. However, water's exact density depends on both the air pressure and the temperature of the area. These variations in density are very slight though, so unless you need to know very exact calculations or the experiment takes place in an area with an extreme temperature/pressure, you can continue to use 1 g/cm 3 for water density. You can look at the chart in the next section to see how water's density changes with temperature.

What is the definition of density?

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 key to solving for density is to report the proper mass and volume units.

How to measure displacement?

To measure the toy's volume, fill a graduated cylinder about half way with water. Record the volume. Add the toy. Make sure to displace any air bubbles that may stick to it. Record the new volume measurement. The volume of the toy soldier is the final volume minus the initial volume. You can measure the mass of the (dry) toy and then calculate density.

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.

Water Density

If you're still in school, you've probably heard this statement in your science class: " Density is the mass per unit volume of a substance". On Earth, you can assume mass is the same as weight, if that makes it easier.

Water's density varies with temperature

Growing up with an older brother was difficult, especially when he had his friends over, for their favorite activity was thinking of ways to antagonize me. I was able to use water density once to at least play a trick on them, though. One hot summer day they climbed the huge hill next to our house to dig a hole to hide their bottle-cap collection.

Ice is less dense than water

If you look at this picture you can see that some of the iceberg is below the water level. This is not a surprise, but actually almost all of the volume of an iceberg is below the water line, not above it. This is due to ice's density being less than liquid water's density. Upon freezing, the density of ice decreases by about 9 percent.

We said ice floats on water, but what about "heavy ice"?

We already said ice floats on water because it is less dense, but ice of a special kind can be denser than normal water. "Heavy ice" is 10.6 percent denser than normal water because the ice is made from "heavy water".

What does density tell us about a substance?

One of these properties is density, which tells us the amount of a certain substance that is to be found per unit volume. This means, it expresses the mass per cubic meter, liter or any other volume unit of the substance ...

What determines how tightly packed a substance is?

The size of the empty spaces between the molecules that compose a substance determines how tightly packed the substance is. This means that the less empty space there is per unit volume of a certain substance, the more molecules there will be inside that volume. Let’s think of an example to clarify this:

Why is density important?

Density is an important property of substances because it tells us not only how tightly packed their molecules are, but also how it could behave under certain circumstances.

Why is it important to know where density comes from?
