## How do you calculate per mole?

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).

## What is 1 mole mean?

The Mole in Current Textbooks

A mole is **the amount (10) of material containing 6.02214 × 10 ^{23} particles**. 1 mol = 6.02214 × 10

^{23}particles. This number is also called Avogadro’s number… … Notice that the definition of the mole is an amount of substance.

## Why is a mole 6.022 x10 23?

The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×10^{23}**elementary entities of the substance**.

## How is the mole defined class 11?

A mole can be defined as **the amount of substance that contains the same number of chemical entities (atoms, ions, molecules, etc.)** as there are in 12 g of Carbon-12 isotope, as defined by the General Conference on Weights and Measures. Complete step by step answer: … 1 mole of carbon = 12g of carbon.

## Why do we use carbon-12 as a standard?

Carbon-12 is the **standard while measuring the atomic masses**. Because no other nuclides other than carbon-12 have exactly whole-number masses in this scale.

## Why is carbon-12 the standard for moles?

as there are atoms in exactly 12 grams of carbon-12 (i.e., 6.022 X 10^{23}). So the mole is the title used **for the amount 6.022** x 10^{23} 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 10^{23} donuts and a serious stomach ache.

## What is mole class 12th?

Calculate the mole fraction of H2SO4. in a solution containing 98% H2SO4. Hint: Mole fraction can be defined as the **ratio of number of moles of one component** to the total number of moles of all the components. … This includes the solvent and solute present in the solution.

## What is mole concept in short answer?

Mole is defined as **the amount of the substance containing the same number of discrete entities (atoms, molecules, ions, etc) as there are atoms in a sample of pure 1**2C weighing exactly 12g. The number of particles present in one mole of any substance =Avogadro Number=6.
