Question

How many electrons are present in 4.4gc{{o}_{2}}co 2 ?

Answer 1

the electrons are 2

hope this helps you..

Answer 2

1 mole of CO2 = 44g = 6 * 10²³ molecules

Number of electrons in 1 molecule of CO2 = 6 + 8*2

= 22 electrons

Given mass of CO2 = 4.4 g

Number of moles = Given mass / Molar mass

= 0.1 moles

Therefore ,

Therefore number of molecules in 0.1 molecules = 6 * 10^22 molecules

Hence,

Number of electrons = 6 * 10²² * 22 electrons
