Vedclass · Answer

(C) The chemical formula of ethane is $C_2H_6$ $(CH_3-CH_3)$.Each carbon atom has $6$ electrons and each hydrogen atom has $1$ electron.Total electrons in one molecule of ethane $= (2 	imes 6) + (6 	imes 1) = 12 + 6 = 18$ electrons.One mole of ethane contains $N_A$ molecules,where $N_A = 6.022 	imes 10^{23} \ mol^{-1}$.Total electrons in one mole of ethane $= 18 	imes 6.022 	imes 10^{23} = 108.396 	imes 10^{23} \approx 108.4 	imes 10^{23}$.Therefore,the correct option is $(C)$.

What is the total number of electrons present in one mole of ethane?
