In 22400 ml there are Na atoms
so in 1 ml there will be Na / 22400 atoms
so 36 ml there will be Na / 22400 * 36 atoms .

caco3 --> cao + co2
1mole of caco3 gives 1 mole (22400 ml ) of co2
or 22400 ml of co2 is produced by 1mole of caco3
1 litre of co2 is produced by 1/ 22.4 mole of caco3
.56 litres of co2 is produced by 1/ 22.4 * .56 moles of caco3.
