text: 1 gram of any sample contains 1 mole of molecules. No it is NOT , it's only true for protons!
  Two or more atoms of same kind come together to form a molecule.
  Mole is a unit that is used repeatedly in introductory chemistry classes.
  Eg. 1.0 grams of H2 is equal to 0.5 mole H2 and it contains 3.011 x 1023 H2 molecules
  and 1.0 grams of O2 is equal to 0.03125 mole O2, it contains 1.882 x 1022 O2 molecules
  A mole is larger than a molecule. A mole represents a specific quantity of molecules (6.022 x 10^23) in chemistry, while a molecule is a single unit of chemical compounds made up of atoms.
  A mole is usually bigger than the molecule. In one mole there are will be 6.02x10^23 molecules which makes the mole bigger between the two.
  The molar mass of oxygen is approximately 16 grams per mole. This means that one mole of oxygen molecules (O2) would have a mass of 32 grams, since each molecule of O2 consists of 2 oxygen atoms.
  One mole of hydrogen molecules (H2) contains 2 hydrogen atoms per molecule, while one mole of hydrogen atoms contains single hydrogen atoms. Since the mass of a hydrogen atom is approximately half the mass of a hydrogen molecule, the molar mass of hydrogen molecules is higher than the molar mass of hydrogen atoms.
  The mass in grams of 1 mole of the compound (apex)
  There are 6.022 x 10^23 molecules in one mole of sulfur molecules.
