Vedclass · Answer

(D) Mass of one electron = $9.108 	imes 10^{-31} \ kg$. Number of electrons in $1 \ mole = 6.023 	imes 10^{23}$. Mass of $1 \ mole$ of electrons = $(9.108 	imes 10^{-31}) 	imes (6.023 	imes 10^{23}) \ kg = 9.108 	imes 6.023 	imes 10^{-8} \ kg$. Number of moles that weigh $1 \ kg = \frac{1}{9.108 	imes 6.023 	imes 10^{-8}} = \frac{1}{9.108 	imes 6.023} 	imes 10^8 \ moles$.

How many moles of electrons will weigh $1 \ kg$?
