Question

calculate the number of atom in 11 gram of co2​

Answer 1

Explanation:

relative molevular mass of co2 is 44.(O=16,C=12).so the number of atoms in 44g is 6.022×10^23(avegadro constant).therefore the number of carbon atoms in 22g is 6.022×10^23/2.as in one atom there is only one atom of carbon. thus 22gm CO2 has 3.011x10^23 C atoms.
