How many strings in a drop of water

[hsara]

Assuming strings are real, how many would fit in a drop of water? Perhaps this is a basic math question, or that the question itself does not make sense given the hypothetical and (currently) unobservable nature of strings.

According to: http://en.wikipedia.org/wiki/Orders_of_magnitude_(length ) a drop of water is 10^ -5 meters and the Planck length is 10^ -35 meters. So (10^-5-(-35))^3 = 10^90: A one with 90 zeros? Would this be a relatively accurate ballpark number of strings fitting inside a particle of water?

It would probably be better to estimate the number of fundamental particles (i.e. strings) that compose a drop of water. I.e. find the number of moles of H20... find the number of electrons and quarks...
