How many water molecules are there in a cell?

A water molecule has two hydrogen atoms and an oxygen atom

Everyone should know that the size of cells varies, from tiny granule cells in the cerebellum to a large fertilized ovum.  Needless to say, the size of molecules within the cell varies from tiny water molecules consisting of just two hydrogen atoms and an oxygen atom, to enormous DNA molecules consisting of hundreds of millions of base pairs.  Keep in mind that water represents 99% of the molecules in a cell.   It is interesting to know that the human body consists of between 10^13 and 10^14 cells.
