Answer 2

Answer:

0.55 mg

Explanation:

We know that,

The mass of 1 electron =9.1×10−31kgwhich is equivalent to 9.1×10−25mg

1mole of electron = 6.02×1023electrons

For getting the mass of 1 mole of electrons we must multiply the mass of an electron with 1 mole of electrons

i.e. Mass of 1 mole of electrons = mass of 1 electron ×number of one mole of electron

=(9.1×10−25)×(6.02×1023)

=0.54782mg

≈0.55mg

∴The mass of one mole of electrons =0.55mg
