How many molecules are in a mole of h2o?
6.022 x 1023 water A mole of water has 6.022 x 1023 water molecules.
How many moles are in 2 molecules of water?
One mole of H₂O contains 6.023 × 10²³ number of H₂O molecules. This is so because 1 mole of any substance contains the amount of 6.023 × 10²³ constituents in it, also known as the Avogadro number. Thus, 2 moles of H₂O will contain 2 × 6.023 × 10²³ number of H₂O molecules, that is 12.046 × 10²³ molecules of H₂O.
How do you find how many moles are in molecules?
Converting between molecules and moles is done by either multiplying by or dividing by Avogadro's number:
- 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.
