Hi everyone its my first time here, read the forums greatly though and have been a help in understanding but now I am completely lost on this problem: Calculate the number of coulombs of positive charge in 250 cm^3 of (neutral) water (about a glass full). So far I tried converting the volume to m^3 (2.5E-4 m^3, not sure if it matters.)then tried tried dividing by colulomb's constant and ended up with units kg/s^2 * c^2 and don't know where to go from there. I am not sure if I really approached this problem right as the section it supposedly comes from keeps mentioning q=ne, but I cannot relate that directly. I am thinking I am missing something inbetween , any ideas to go about the problem would be appreciated.
