The answer depends on the composition of the molecule.
molecular mass
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 atomic mass unit is 1.660538921(73)×10−27 kg. 1 gram contain 0,6022.1024 atomic mass units.
A normal water molecule weighs roughly 18 Amu's, so one mole of water weighs 18 grams. -KRogersaurus
the number of positive charges or protons in the nucleus of an atom of a given element, and therefore also the number of electrons normally surrounding the nucleus. (atomic number) The mass of a given atom or molecule, expressed in atomic mass units. (atomic mass)
28 atomic units
A molecule is the smallest unit with the characteristic properties of a molecular substance, i.e., one joined by covalent bonds. A single atom is the smallest unit with the characteristic properties of an elemental substance.
- calculate the molecular mass of the substance from the atomic weights of the contained elements - 1 molecule gram of any substance contain 6,023 141 79.1023 molecules (Avogadro number) - mass of a single molecule is: Molecular mass in grams/Avogadro number
A mole.
