(A) The mass of one electron is $9.109 	imes 10^{-31} \, kg$.$1$ mole of electrons contains $6.022 	imes 10^{23}$ electrons.Mass of $1$ mole of electrons = $(9.109 	imes 10^{-31} \, kg) 	imes (6.022 	imes 10^{23}) \approx 54.85 	imes 10^{-8} \, kg$.Converting to milligrams $(mg)$: $54.85 	imes 10^{-8} \, kg = 54.85 	imes 10^{-5} \, g = 0.5485 	imes 10^{-3} \, g = 0.5485 \, mg \approx 0.55 \, mg$.
