Calculate the number of electron in 100gms of CO2

Molar mass of carbondioxide =12+2×16 = 44g. So, No. of mole in 100 g of CO2 =weight/Molar mass = 100/44 =2.27 mol. No. of molecules in CO2 = 2.27 × Avogadros number. So, Total number of electrons in 100 g of CO2 =22×2.27×Avogadros number =49.94 ×Avogadros number.
