SUMMARY
The discussion confirms the assertion that there are more atoms in a cup of water than there are cups of water in the oceans. A standard cup of water, approximately 236.6 grams, contains about 7.8 x 1024 molecules of water, calculated using the molecular mass of water (18 g/mol) and Avogadro's number. In contrast, the total volume of Earth's oceans translates to roughly 2.2 x 1019 cups of water. This results in a factor of approximately 350,000, indicating that there are over a quarter million times more molecules in a cup than cups in the ocean.
