Mole Facts
Mole is a unit of measurement used in chemistry and other related fields like biochemistry and biophysics. It is one of the recognized units of measurement in the International System of Units, related to Avogadro's Constant, and is represented by the abbreviation "mol."
Interesting Mole Facts:
Avogadro's Constant defines a mole as having a value of 6.02214129(27) x 1023, as it refers to the number of particles of a substance.
The basic correlation is that a mole is the amount of any known or unknown substance that has as many elementary entities as there are atoms in twelve grams of pure carbon-12.
That means that one mole of pure C-12 must have a mass of twelve grams in order for the unit of measurement to line up.
The number of elementary entities in any substance is known as its chemical amount, which makes the mole an easy to use unit of measurement for chemical amounts.
In chemistry, a mole is a more convenient standard unit than attempting to measure in mass or volume, especially in chemical equations.
The representation in measurement is further simplified by the concept of the molecular mass, which states that the mass of one mole of a substance (measured in grams) is equal to the molecular mass.
Therefore, one mole of a substance is equal to the molecular mass of the same substance.
The development of the mole as the standard unit of measurement for calculating the elementary entities contained within a substance has a history that dates back to the first table of relative atomic mass, crafted by John Dalton in 1805.
Later, Jons Jacob Berzelius was instrumental in redefining relative atomic mass with a greater degree of accuracy.
For some time, hydrogen and then oxygen-16 became the standard for comparison in measuring units, following the use of mass spectrometry.
Wilhelm Ostwald coined the term mole in 1894, shortened from the German word for molecule.
There has been controversy over the use of the mole as a standard unit of measurement since its formal adoption in 1971, largely because scientists have long known that knowing the mass of a substance is not always necessary for measurement.
While those who work in a chemistry field rely on the mole as a unit of measurement, its application for industry is impractical since the amount is so small.
The kilomole was introduced to define larger sample units, which is the number of entities in twelve kilograms of carbon.
As of 2011, the governing body over weights and measures agreed to investigate alternatives to the mole.
