Question

how are the values for q1 and q2 = 6.02 e^-19C ? if the hydrogen and oxide ions are both equal to one elementary charge, shouldnt their charge be 1.602 e^-19C ? Can you please explain the conversion factors you used to get 6.02 e^-19C?

Answer 1

I think it shold be the value of one elementary charge:

$$e=1.602\cdot10^{-19}C$$
