Answer #1

electrons would be required to have a mass equivalent to one hydrogen atom = Na

Thus, Na = (mass of a hydrogen atom)/(mass of an electron)

                   = (1.67x 10-27)/(9.1x 10-31)

                   = 1833.15

Thus, electrons would be required to have a mass equivalent to one hydrogen atom = 1833.15
