    18g of water has 6.023x10^23 molecules (that's 1 followed by 23 zeroes). Since each water molecule has 3 atoms, the number of atoms in 18g of water is 3X that number. A cup of water has 236g, so each cup of water has 7.9x10^24 molecules.

    The volume of the world's oceans is 1.3x10^9 cu km or 1.3x10^24 cu cm. So, there are more molecules in a cup of water than there are cc of water in the world's oceans.

    Cool stat, brah!

      fuck molecules. single atoms is what the fuck this is all about!

        Multiple the molecule number by 3.

              Avogadro rocks. Seriously, dude was a stud.

              If this doesn't epitomize cool, I don't know what does...

                  Avogadro was a chemist from the late 18th century to the mid 19th century. He was the first to postulate that 1 mole (equal to the atomic weight of the molecule of the compound in grams) of any compound contains 6.023 x 10^23 molecules (or atoms if it was an element). The number is called the Avogadro number. Brilliant guy. Like the speed of light or the charge of an atom, the Avogadro number is one of the most important numbers in science.

                    But did he know there were more atoms in a glass of water?

                        LOL.. probably not. I don't think he knew how much ocean surface area the earth had or how deep the oceans were.

                          You clearly don't go to the same parties I do.
