how many atoms are in4.39g of CO2
The molecular mass of Carbon dioxide
 is 44g/mol
Caculation of molar mass of Carbon dioxide
:

44g of CO2 contains that means 1 mole of CO2 (1C and 2 O) contain 1 mole of C-atom and 2 mole O-atom
Or else we can write as 44g of CO2 contains 3 mole of atoms

Hence 4.39g of CO2 contains
