So a mole of water is 6.02 x 10 23 molecules . Correspondingly, how many atoms are in 2 moles of h2o? (Example #1) 0.200 mole of H 2 O contains how many molecules? [The • represents seven units of H2O attached to one unit of MgSO4.] For example, since one atom of oxygen will combine with two atoms of hydrogen to create one molecule of water (H 2 O), one mole of oxygen (6.022×10 23 of O atoms) will combine with two moles of hydrogen (2 × 6.022×10 23 of H atoms) to make one mole of H 2 O. One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms. In one mole of water, there will exist approximately 6.02 ⋅ 1023 water molecules. 76.4 g of .
