Question

Nu of electron in 100 gm co2

Answer 1

44 gm of CO2 contains 6.022×10^23 atoms.
in each atom, there are 6 electrons.
therefore,
44 gm of CO2 contains = 6×6.022×10^23 electrons.
therefore,
1gm of CO2 contains = (6.022×10^23×6)÷44 electrons.
100 grams of CO2 contains =(6×6.022×10^23×100)÷44 electrons.
=(6×6.022×10^25)÷44 electrons.

Answer 2

Number of moles of co2 = 100/44

Number of moles of electrons = 22×100/44=50

Number of electrons = 50NA = 300×10^23 OR 3 × 10^25
