1. 6.022 X 1023 is Avogadros number (Avogadros constant) the number of atoms in a mole.
No.
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.
Avogadros number (approximately). The atomic weight of iron is 55.845. Avogadros number , the number of atoms in a mole of an element, or the number of molecules in a mole of a compound is 6.023 X 1023
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
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.
The number of molecules in a mole is Avogadros number, 6.023 X 1023 there are 5 atoms in each molecular formula unit so we then get 6.023x1023 x 5 =3.115 X 1024 atoms.
1 mole has 6,022 140 857 (74).1023 molecules, atoms, ions.
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
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
