en.wikipedia.org/wiki/Mole_(unit)

The mole is the unit of measurement for amount of substance in the International System of Units (SI). The unit is defined as the amount or sample of a chemical substance that contains as many elementary entities, e.g., atoms, molecules, ions , electrons, or photons, as there are atoms in 12 grams of carbon-12 (12C), the ...

For example, one mole of grapefruits would be as big as the earth. ... However, most chemical writing uses mol/dm3, or mol dm-3, which is the same as mol/L. These units are often written with a capital letter M (pronounced "molar"), sometimes preceded by an SI prefix, for example, millimoles per litre (mmol/L) or millimolar ...

Oct 23, 2013 ... Moles are no different. You can have a mole of molecules or people or cheeseburgers. But there are a lot more than twelve things in a mole — there are 6.02 x 1023. That's 602,000,000,000,000,000,000,000 things. Because the mole contains so many units, they're most often used in chemistry is a way of ...

The word “mole” suggests a small, furry burrowing animal to many. But in this lesson, we look at the concept of the mole in chemistry. Learn the incredible magnitude of the mole--and how something so big can help us calculate the tiniest particles in the world.

Unfortunately, the clumsy definition of the mole obscures its utility. It is nearly analogous to defining a dozen as the mass of a substance that contains the same number of fundamental units as are contained in 733 g of Grade A large eggs. This definition completely obscures the utility of the dozen: that it is 12 things! Similarly ...

Instead of being used for things we encounter in daily life, the mole is used by scientists when talking about enormous numbers of particles like atoms, molecules, and electrons—although the mole's usefulness goes beyond being a helpful scientific term. The mole does more than represent a big number: It provides a key ...
