Who created the mole?

On this day in 1776, Amedeo Avogadro, an Italian scientist known as one of the founders of physical chemistry, was born. Avogadro studied the properties of electricity and liquids, but his best known work was with gases.

How do chemists use the mole?

Because atoms, molecules, and other particles are all extremely small, you need a lot to even weigh them, so that’s why chemists use the word “mole.” Keep in mind that not everything weighs the same if you have a mole of it. A mole refers to the number of particles you have, not the mass.

Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules. The law is approximately valid for real gases at sufficiently low pressures and high temperatures.

How much is a mole?

The mole, abbreviated mol, is an SI unit which measures the number of particles in a specific substance. One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.

How big is a mole chemistry project?

Because the mole contains so many units, they’re most often used in chemistry is a way of measuring really really small things like atoms or molecules. So a mole of water is 6.02 x 1023 molecules of water, which works out to be about 18 grams, or 18 mL. A mole of aluminum is about 26 grams.

Is a mole a molecule?

A mole is a certain quantity of molecules, namely the Avagadro number of molecules NA=6.023×1023. So for example if you take 6.023×1023 water molecules then that makes up 1 mole of water. By definition, 1 mole is said to be the number of particles contained in 12g of the carbon-12 isotope.
