6.0221 x 1023 atoms/molecules/entities make up one mole. It is known as Avogadro's number.
This is a consequence of the definition of one mole, rather than being the cause of the definition of a mole. It is not necessary to know this number for the majority of calculations using moles.

How many no of molecules are present in one mole of CO2 gas?
There are approximately 6.022 x 10^23 molecules in one mole of CO2 gas. This number is known as Avogadro's number and represents the number of particles (atoms or molecules) in one mole of a substance.
How many moles are there in 12.04 x 1023 atoms Hellium?
There are 2 moles of Helium atoms in 12.04 x 10^23 atoms of Helium. This is because Avogadro's number represents the number of atoms, ions, or molecules in one mole of a substance, and in this case, it is 6.022 x 10^23 entities in one mole.
How many atoms does one mole of carbon-12 have?
One mole of carbon-12 contains 6.022 x 10^23 atoms. This value is known as Avogadro's number and represents the number of particles (atoms, molecules, ions) in one mole of any substance.
How does the number of atoms in one mole of beryllium compare with the number of atoms in one mole of magnesium?
One mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Beryllium and magnesium are both in Group 2 of the periodic table, so they have the same number of atoms in one mole.
How many mole is in one atom of hg?
One atom of mercury (Hg) contains roughly 6.022 x 10^23 atoms, which is known as Avogadro's number. Thus, there is one mole of mercury atoms in one atom of Hg.
What number on the periodic table represents the mass in grams of one Mole of atoms in an element?
The number on the periodic table representing the mass in grams of one mole of atoms in an element is called the molar mass, which is expressed in grams per mole. It is numerically equal to the atomic mass in atomic mass units (amu) of the element.
How does the number of atoms in one mole of beryllium compare with the number of atoms in one mole of magnesium?
One mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Beryllium and magnesium are both in Group 2 of the periodic table, so they have the same number of atoms in one mole.
How many atoms are in one mole of yttrium?
The answer is 0.0112478537689.
Is H an atom in chemistry?
H is the chemical symbol for Hydrogen and represents one hydrogen atom everywhere other than in a chemical equation where it represents one mole of hydrogen atoms.
How many atoms are in one mole of methane?
