Mole, standard unit (6.02214076 x 10^23) in chemistry for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s const
Using Avogadro's Number to Calculate the Number of Molecules Say you have 2 moles of NaCl. How many molecules of NaCl is that? Here's where you can use Avogadro's number: \(\mathrm{2mol\enspace NaCl\Biggl(\dfrac{6.022\times10^{23}\enspace molecules\enspace NaCl}{1mol}\Biggr)=...
To go from moles to molecules, multiply the number of moles by 6.02 x 1023. To go from molecules to moles, divide the numbers of molecules by 6.02 x 1023. For example, if you know there are 3.35 x 1022water molecules in a gram of water and want to find how many moles of water th...
