## The mass and charge of one mole of electrons respectively class 11 chemistry CBSE

The mass and charge of one mole of electrons respectively is A 548 times 10 7Kg 965 times 104C B 548 times 10 7Kg 965 times 103C C 548 times 10 7g 965 times 104C D 548 times 10 7Kg 965 times 104C

The mass and charge of one mole of electrons, respectively is:(A) 54.8× 10 −7 54.8×10−7 Kg, 9.65× 10 4 9.65×104 C (B) 5.48× 10 −7 5.48×10−7 Kg, 9.65× 10 3 9.65×103 C (C) 5.48× 10 −7 5.48×10−7 g, 9.65× 10 4 9.65×104 C (D) 5.48× 10 −7 5.48×10−7 Kg, 9.65× 10 4 9.65×104 C Answer Verified 152.9k+ views 4 likes

**Hint:**We know that 1 mole of any substance will have

6.02× 10 23 6.02×1023

units (Avogadro number) of that substance. Also the charge of 1 electron is

1.6× 10 −19 1.6×10−19

C and the mass of 1 electron is

9.1× 10 −31 9.1×10−31

Kg. So, to find the charge and mass of 1 mole of electrons, find the product of the number of electrons present in 1 mole and the mass/charge of 1 electron.

**Complete step by step answer:**

-Let us start by just writing down the charge and mass of 1 electron.

The charge of 1 electron is

1.6× 10 −19 1.6×10−19

C and the mass of 1 electron is

9.1× 10 −31 9.1×10−31 Kg.

-We know that 1 mole of any substance has

6.02× 10 23 6.02×1023

units (Avogadro number) of that substance. Hence we can say that when we say 1 mole of electrons we are referring to

6.02× 10 23 6.02×1023 electrons.

-Now, we will calculate the mass of 1 mole of electrons.

Mass of 1 electron =

9.1× 10 −31 9.1×10−31 Kg

Number of electrons in 1 mole =

6.02× 10 23 6.02×1023

Therefore the mass of 1 mole of electrons =

9.1× 10 −31 ×6.02× 10 23 9.1×10−31×6.02×1023 Kg = 5.48× 10 −7 5.48×10−7 Kg

Hence the mass of 1 mole electron of electrons is

5.48× 10 −7 5.48×10−7 Kg.

-Now, we will calculate the charge of 1 mole electrons.

Charge of 1 electron =

1.6× 10 −19 1.6×10−19 C

Number of electrons in 1 mole =

6.02× 10 23 6.02×1023

Therefore the charge of 1 mole of electrons =

1.6× 10 −19 ×6.02× 10 23 1.6×10−19×6.02×1023 C = 9.65× 10 4 9.65×104 C

Hence the charge of 1 mole of electrons will be

9.65× 10 4 9.65×104 C.

**So, the correct answer is “Option D”.**

**Note:**We all know that there exist three types of particles which constitute an atom: electron, proton and neutron. A proton has a charge equal in magnitude with the electron but with opposite charge and is equal to =

+1.6× 10 −19 +1.6×10−19

C while the charge of an electron is =

−1.6× 10 −19 −1.6×10−19

C. A neutron is a neutral atom with 0 charge. Remember that this charge is always in units of Coulomb (C) and the mass we take here is in Kg (kilogram).
