One mole of electrons are present in----- grams of methane

Each carbon atom, C612 contains….6 protons, 6 electrons and 6 neutrons ;Each hydrogen atom, H11 contains….1 proton, 1 electron and zero neutrons ;Thus each molecule of CH4 contains…10 protons, 10 electrons and 6 neutrons ;Thus each mole (16 g) of CH4  contains…10 moles (10 NA) of protons, 10 moles (10 NA)  of electrons and 6 moles (6 NA)  of neutrons ;Each molecule of CH4 contains……4 sigma bonds ;Each mole of CH4 contains……4 moles (4 NA) sigma bonds ;Each mole of CH4 occupies….22.4 litres at STP ;Each mole of CH4 contains….1 gram atom or 1 mole atom or 1 mole of carbon ;Each mole of CH4 contains….4 gram atoms (4 NA) or 4 mole atoms (4 NA)  of hydrogen ;
