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
The unit is "per mole", or mol^-1.
atoms in 12 g of c-12
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.
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.
No.
moles to atoms you multiply the number of moles by avogadros number ex: 1.32 mol x (6.022 x 10^23 atoms)/mol mass to atoms you multiply the mass (in grams) times the molar mass of the element or compound (ex: N 14.01 mols/gram) then times avogadros number once you have the moles. ex: 45.6 g N x (14.01 mol/gram) x (6.022 x 10 ^23 atoms/mol) if it's a compound instead of an element, find the molar mass of the compound (the molar masses of all the elements in it added up) and multiply by it. ------------------------- Actually you are wrong, from mass to atoms you need to take the initial mass divide by the gram of the element that you are doing and multiply by the Avogadros number
The mass of a single atom would be the mass of one mole of that element, divided by Avogadros number. So for example calcium, Ca, would be 40/6.02214129×1023 mol−1
You don't need to use Avogadro's number, you need the mass of the molecule in atomic units. Mass / molecular mass = moles eg for water, 36 grams / 18 atomic units = 2 moles

1. 6.022 X 1023 is Avogadros number (Avogadros constant) the number of atoms in a mole.
You can work this out by dividing the molecular mass of calcium, 40, by Avogadros number, 6.02214129(27)×1023 mol−1 This will give you the answer as the molecular mass of an element is the combined weight of the number of atoms that make up one mole, which is the same as Avogadros number.
Its avogadros number
A mole.
2.11 x 10^22 This is how you figure it out: 3.78g divided by 107.87(the atomic mass of silver). Then you multiply the number you get by 6.022x10^23 (Avogadros number). And that's your answer.
6.02*10^23atoms (avogadros constant)
6.02*10^23atoms (avogadros constant)
