6.022x10 23
One mole in chemistry represents Avogadro's number of particles, which is approximately 6.022 x 10^23. It is a unit used to express amounts of chemical substances.
One mole is a quantity used to describe a group containing its 6.022 x 1023 particles.For example :-Substance quantity mass(g)carbon one mole 6oxygen one mole 16nitrogen one mole 14Hydrogen one mole 1silver one mole 108sodium chloride one mole 58.5
The total number of molecules is equal.
Avogadro's number is the number of "elementary entities" (usually atoms or molecules) in one mole. It is 6.0221415 × 1023
Both one mole of carbon and one mole of sodium contain Avogadro's number of atoms, which is approximately 6.02 x 10^23 atoms. This quantity is true for all elements or substances when considering one mole.
The number of particals (molecules, atoms, ions etc.) in one mole of ANY substance is the same: 6.022*1023 (Avogadro's number)
Using the term "percent" is redundant when referring to a portion of a larger quantity, as percent by definition already means one out of 100. It is more correct and clearer to simply state the percentage as a fraction or decimal instead.
It is the number of atoms or molecules of a compound in one mole of that substance.
The average weight in grams of one mole of the element.

The measure of the quantity of matter is mass. Mass is a fundamental property of an object that determines its resistance to acceleration. It is typically measured in units such as kilograms or grams.
