The unit is "per mole", or mol^-1.
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
Avogadro's number represents the number of units of a substance in one mole of the substance. These units may be electrons, atoms, ions, or molecules, depending on the substance.
By saying Avogadro's number of atoms, you are saying one mole (or 6.02 × 1023 atoms). And one mole of any elements is its atomic mass. Phosphorus' atomic mass is 31.0 grams
1 mole of gas at STP occupies 22.4 liters.
A mole.
The unit is "per mole", or mol^-1.
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.
There is 1 mole of atoms in 6.022 x 10^23 atoms of any element.
A mole of any substance has the Avogadro's number of such units. As an example, a mole of hydrogen atoms is equivalent to 6.022 x 1023 atoms.
Avogadro's number represents the number of units of a substance in one mole of the substance. These units may be electrons, atoms, ions, or molecules, depending on the substance.
Its avogadros number which is 6.02 X 10^23 g/mol
Avogadro's number (generally written as 6.02 x 10^23) is the number of atoms or molecules it takes to have one mole of a particular atom or molecule. For example, one mole of Hydrogen is just 6.02 x 10^23 atoms of hydrogen.
1 mole has 6,022 140 857 (74).1023 molecules, atoms, ions.
To find the number of atoms in 55.8 grams of Fe, you need to first calculate the moles of Fe using the molar mass (55.85 g/mol). Then you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
By saying Avogadro's number of atoms, you are saying one mole (or 6.02 × 1023 atoms). And one mole of any elements is its atomic mass. Phosphorus' atomic mass is 31.0 grams
One mole of photons would contain approximately 6.022 x 10^23 photons. This number is known as Avogadro's number and represents the number of particles in one mole of any substance. Each photon carries energy and has characteristics of both particles and waves.
