Expert Answer:

H2, molecular hydrogen contain, a total of 2 protons and 2 electrons.

1 mol of H2 will contain 6.023x1023 H2 molecules.

1 molecules due to 2 protons a charge of, +2x1.609x10-19 C

Hence 6.023x1023 H2 molecules contain, 6.023x1023x2x1.609x10-19 C = 9.38 x 104 C = 0.094 MC of positive charge, or equivalently the same amount of negative charge. Bu the net charge will be zero.
