The term ‘mole’ represents a number, in the same way the word ‘dozen’ represents 12 of something. In this case, one mole represents the enormous (and slightly strange) number, 6.02 x 1023.

## What is meant by 1 mole?

A mole is the amount(10) of material containing 6.02214 × 1023 particles. 1 mol = 6.02214 × 1023 particles. This number is also called Avogadro’s number…

## Is to a mole like 12 is to a dozen?

The mole is a unit for counting 6.02 1023 representative particles. The dozen is used to count 12 items.

## What is a mole chemistry simple definition?

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

## Is a mole equal to a gram?

Measuring Mass in Chemistry

One mole (abbreviated mol) is equal to the number of atoms in 12 grams of carbon-12; this number is referred to as Avogadro’s number and has been measured as approximately 6.022 x 1023.

## What is Mole on human body?

Moles are a common type of skin growth. They often appear as small, dark brown spots and are caused by clusters of pigmented cells. Moles generally appear during childhood and adolescence. Most people have 10 to 40 moles, some of which may change in appearance or fade away over time.

## What is the importance of a mole?

THE mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.

## What is a mole Class 9?

The mole is the amount of substance that contains the same number of particles (atoms/ ions/ molecules/ formula units etc.) as there are atoms in exactly 12 g of carbon-12. • Mass of 1 mole of a substance is called its molar mass.

## How 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.

## How many pennies are in one mole?

1 Expert Answer

1 mole of pennies = 6.02×1023 pennies (that’s a lot of pennies).

## How big is a mole of donuts?

So the mole is the title used for the amount 6.022 x 1023 much the same way the word “dozen” is used for the amount 12. So if you had a mole of donuts you would have 6.022 x 1023 donuts and a serious stomach ache.

## What is the formula of mole concept?

This formula can be written as: Number of Atoms or Molecules = (Number of Moles)*(6.022*1023) The relationship between the atomic mass unit (amu) and the gram is given by: 1 amu = (1gram)/(6.022*1023) = 1.66*10-24 grams. Therefore, the mass of one mole of an element will be equal to its atomic mass in grams.

## Are moles and molecules the same?

A mole of a substance is equal to as many molecules of that substance as there are atoms of carbon-12 in exactly 12 g of carbon-12. … Most important of all, by this definition, 1 mole of any substance contains the same number of molecules.
