The number of atoms or other particles in a mole is the same for all substances. The mole is related to the mass of an element in the following way: one mole of carbon-12 **atoms has 6.02214076 × 10 ^{23} atoms** and a mass of 12 grams.

## What is the 12 in carbon?

The 12 in carbon-12 is **the mass number of the isotope**. This means that all atoms of carbon-12 have a mass of 12 atomic mass units.

## What is a compound with 12 moles of carbon?

So, 1 mole of **sucrose** contains 12 moles of carbon atoms, 22 moles of hydrogen atoms, and 11 moles of oxygen atoms.

## 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 a mole similar to a dozen?

Explain how a mole is similar to a dozen. The mole is a unit for counting **6.02 1023 representative** particles. … Each one-mole quantity has 6.02 1023 particles (atoms), but they will have different masses. State the conversion factors needed to convert between mass and moles of the element fluorine.

## What is the relationship between mole and Avogadro number Brainly?

Answer: Avogadro’s number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to **6.022 × 1023 mol-1and** is expressed as the symbol NA.

## How do moles relate to atomic mass Brainly?

The molar mass of a substance is the mass (in grams per mole) of 6.022 × 10 23 atoms, molecules, or formula units of that substance. In each case, the number of grams in 1 mol is the same as the number of atomic mass units that describe the atomic mass, the molecular mass, or the formula mass, respectively.

## What is the difference between a mole and Avogadro’s number?

The mole allows scientists to calculate the number of elementary entities (usually atoms or molecules ) in a certain mass of a given substance. Avogadro’s number is an absolute number: there are **6.022 × 1023elementary entities in 1 mole**.
