$1.008 \ g$ and $0.55 \ mg$

Vedclass · Answer

(B) The mass of one proton is approximately $1.673 	imes 10^{-24} \ g$. The mass of one mole of protons is $1.673 	imes 10^{-24} \ g 	imes 6.022 	imes 10^{23} \ mol^{-1} \approx 1.008 \ g$. The mass of one electron is approximately $9.109 	imes 10^{-28} \ g$. The mass of one mole of electrons is $9.109 	imes 10^{-28} \ g 	imes 6.022 	imes 10^{23} \ mol^{-1} \approx 5.48 	imes 10^{-4} \ g = 0.548 \ mg \approx 0.55 \ mg$. Thus,the correct option is $(B)$.

The mass of a mole of protons and electrons is
