Question

How many moles of electrons will weigh 1 kilogram?

Answer 1

mass of electron = 9.1 × 10-³¹ Kg
mass of one mole electrons = 6.023 × 10²³ × 9.1 × 10-³¹ Kg = 5.48093 × 10^-8 Kg
Let number of electron = n
n = 1 Kg/{ 5.48093 × 10^-8} Kg
= 10/5.48093 × 10^7
=1.824 × 10^7

Answer 2

Answer:10^8/9.108*6.023

Step-by-step explanation:wt. Of 1 electron =9.108*10^-31

In 1mloe 6.023*10^23 particles present.

So. In 1 mole 6.023*9.108*10^24*10^-31electron.

1mole electron =6.023*9.108*10^24*10^-31kg

No. of mole in 1kgelectron

=1/9.108*6.023*10^

10^8/9.108*6.023
