Question

Calculate the valency of 88 gram of carbon dioxide in air

Answer 1

Answer:

What is the number of electrons in 88 gram of CO²? Hence 2 moles of CO2 = 88g CO2. Now, every molecule of CO2 has 22 electrons, (8 each of the 2 oxygen atoms & 6 of the carbon atom). So, 88g of CO2 has 2*6.023*10^23*22= 2.65012*10^25 electrons
