Question

The mass of $1$ mole electron is $0.55mg$.

• A. True
• B. False

Answer 1

The correct option is A True

Mass of one electron is $9.1\times {10}^{-28}gm$

So mass of one mole of electronis $(6.02\times {10}^{23})\times (9.1\times {10}^{-28})$

= $0.55\times {10}^{-3}$ gm $=0.55mg$

So, the given statement is true.
