Question

How many moles of electrons will have a mass of
1 kg ?
​

Answer 1

1kg of moles of electrons have a mass of 1.8×10^6

Answer 2

Step-by-step explanation:

Mass of one electron =9.108×10

−31

kg.

Mass of one mole of electrons =9.108×10

−31

×6.023×10

23

=9.108×6.023×10

−8

kg.

The number of moles of electrons that weigh one kilogram =

9.108×6.023×10

−8

1

=

9.108×6.023

1

×10

8
