Final answer:

One mole of H2O corresponds to 6.022 x 10^23 molecules of water. The molar mass of water is 18 g/mol, with 2 moles of hydrogen atoms and 1 mole of oxygen atoms per mole of water.


Explanation:

The definition of a mole is an equality that can be used to construct a conversion factor. One mole of H2O corresponds to 6.022 x 1023 molecules of water (H2O).

The molar mass of water (H2O) is 18 g (16 + 1 + 1), where 16 g is oxygen, and 1 g each is hydrogen. This is the mass of one mole of the substance, typically represented as grams per mole (g/mol).

In two water molecules, there are 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
