Question

What is the mass of one mole of electrons?

• A. $6.023\times {10}^{23}g/mol$
• B. $5.486\times {10}^{-4}g/mol$
• C. $9.108\times {10}^{-28}kg/mol$
• D. $9.108\times {10}^{-24}g/mol$

Answer 1

Answer: (B)

$5.486\times {10}^{-4}g/mol$

Molar mass of the electron is $0.000000548579909amu$

That is nothing but $5.4857\times {10}^{-4}\frac{g}{mol}$.

Hence, option $\left(B\right)$ is correct
