Question

How to calculate number of electron in 100 gm co2

Answer 1

Hey.


Here is the answer.

1 mole of CO2 has 44g and 6.02×10^23 molecules

so, in 100g , no. of moles = 100/44=2.27 moles

So, no. of molecules of CO2

= 2.27×6.02×10^23 = 13.68×10^23 molecules

As, 1 molecule of CO2 has 22 electrons (6+2×8)

So, no. of electrons in 100g = 22×13.68×10^23

= 301×10^23

= 3.01×10^25 electrons of CO2 .

Thanks.
