Question

Calculate the number of molecules present in 22gm of co2

Answer 1

Since 1 mole of CO2 is 44 g... and you have 1/2 of a mole, you have one half the number of molecules in one mole; 6.02 x 10^23/ 2. Since there is only 1 carbon atom in each molecule, this is your answer. thus 22gmCO2 has 3.011x10^23 C atoms. 0.5 mole and 0.5*Na is the total number of molecules.
