calculate the number of atoms of oxygen present in 132 g of CO2 . what would be the weight CO having the same number of oxygen atom?

132g of CO2= 3 moles since 132/44 = 3
(44 is molecular mass of CO2)

1mole= 6.022x10^23 molecules
Therefore 3 moles= 18.066x10^23 molecules.

Since the value of mole is the same for all elements..... No. Of particles remains the same for CO2 and oxygen

Therefore oxygen will have 3 moles Of atoms or 18.066x10^23 atoms.

CO has a molecular mass of 18u.
1 mole= 18g
Therefore 3 moles= 18x3= 54g.
