i was thinking that too it's confusing coz that was the question given to me  no description of any ions :/

The number of coulombs of positive charge would be the sum of the charges of all of the protons.  You should be able to easily calculate the number of protons in a water molecule and likewise the number of water molecules in a given volume.  You'll note that the problem says nothing about net charge.
