I hope this is helpful for you

Answer 2

Answer: no of electrons= 2/9.1*10^-31=0.219*10^31

No of moles of electrons = 0.219*10^31/6.02*10^23=0.036*10^8

=3.6*10^6

Explanation:

First divide 2kg by the mass of one electron to find no of electrons. Then divide no of electrons with avogadro number to find number of moles.
