## What is a chemist dozen?

A mole is a unit of measurement convenient for chemists. Bakers count cookies in groups of **12** and call it a dozen. Chemists count molecules in groups of a much larger number, 6 x 10^{23}, and call it a mole. A mole is simply a “chemist’s dozen.”

## Why do chemists use the word 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.

## What is a dozen mole?

Chemists use the term mole to represent a large number of atoms or molecules. Just as a dozen implies **12 things**, a mole (abbreviated ‘mol’) represents 6.022 × 10^{23} things.

## What is the mole in science?

The mole is defined as **the amount of substance that contains as many elementary entities as there are atoms in exactly 12 g of carbon-12**.”(

## How a mole is similar to a dozen?

One mole consists of Avogadro’s number of atoms i.e., 6.02×1023 atoms. – The amount of atoms in 12.0 grams of Carbon; 12 is the same as Avogadro’s number as it is for **1 mole of carbon** i.e. a sample of 12 grams of carbon is equal to its one mole. Therefore, it is similar to a dozen.

## Who gave the term mole?

**Wilhelm Ostwald** (1853-1932) introduced the “Mol” (mole in German), probably in 1893 [5]. However, he used this term to mean “molecular weight in gram”: “We generally call one mole the weight in grams that is numerically identical with the molecular weight of a given substance” (translated sentence on page 119, ref.

## Why did Avogadro call it a mole?

The mole is a unit used in chemistry that is **equal to Avogadro’s number**. It is the number of carbon atoms in 12 grams of the isotope carbon-12. The word mole comes from the word molecule. It is not related in any way to the animal called the mole.

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
