Avogadro's number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).

One mole of atoms contains 6 x 10 23 atoms, no matter what element it is. This is a very large number: it is 6 with 23 zeros after it. It is known as the Avogadro number. This number is used in chemistry because if you could count out this many carbon atoms, the total mass of carbon you would have is 12 g.

one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

As it is already known, 1 mole of any substance contains 6.023×10^23 atoms. 1 mole of SO2 contains one sulfur and two oxygen molecules.

1 mole=6.02214076x10^23, # of (Cl) atoms in 1 (Cl) molecule=2, therefore in 1 mole of (Cl) molecules there are 1.204428152x10^24.

Fraction of a mole * Atomic weight = weight or mass you have Now we have to get what fraction of a mole you have. To start, you need know that all a mole means is you have 6.022 x 1023 atoms of that type. So if I tell you I have a mole of nitrogen, then I have 6.022 x1023 nitrogen atoms.

Avogadro's number states that one mole of any substance contains 6.022 * 1023 number of atoms. That means 1 mol of Helium, 1 mole of Copper, 1 mol of gold, and 1 mol of Aluminum, all contain 6.022 * 1023 number of atoms.

( 1/4 of a mole) x (6.02 x 1023 atoms/mole) = approximately 1.5 x 1023 atoms. If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water.

(1 mole of anything is 1 mole. The subscript tells the number of atoms of an element in one molecule. There are 2 moles of carbon in one mole of C2H6.

A mole is a unit of measurement, which equals 6.02 * 10^23. If you have a mole of cl2, then you have 6.02 * 10^23 molecules of cl2. If you want to calculate for atoms however, you can see that each molecule has two atoms of cl. Therefore you have 2* 6.02 * 10^23 chlorine atoms.
