Vedclass · Answer

(C) One mole of electrons contains $6.022 	imes 10^{23}$ electrons.The mass of one electron is $9.1 	imes 10^{-28} \ g$.Therefore,the mass of one mole of electrons is calculated as:$	ext{Mass} = (6.022 	imes 10^{23}) 	imes (9.1 	imes 10^{-28} \ g) \approx 5.48 	imes 10^{-4} \ g$.Converting this to milligrams $(mg)$:$5.48 	imes 10^{-4} \ g 	imes 1000 \ mg/g = 0.548 \ mg \approx 0.55 \ mg$.
