how many mega coulombs of positive (or negative) charge are in 1.00 mole of neutral molecular hydrogen gas ?
or it will contain 2.00 mol of hydrogen nuclei/electron/proton
1 mol electron/proton has 1farad charge=96500coulomb=9.65×10e-2 MCoulomb
hence 2.00 mol will have 0.193MCoulomb charge
In every molecule of H2 there are 2 electrons.So total no. of electrons in 1 mole is = 2*6.022*1023 .
As charge on 1 e is 1.6*10-19 coulombs.
Thus total charge = 2*6.022*1023*1.6*10-19 coulombs=19.2704*104 coulombs=19.2704*10-2 mega coulombs.
