Answer :

Chemical Formula of Limestone is CaCO3


Molecular Mass of Calcium Carbonate = 100 g/mol


10 grams of 100% pure of CaCO3 = 10gm of CaCO3


90% pure CaCO3 means, it will contain = of CaCO3


= 9 gm of CaCO3


Number of moles of CaCO3 =


=


= 0.09 mol


Now,


The reaction is given as follows:



Now according to the above reaction,


1 mole of CaCO3 gives 1 mole of CO2


So, 0.09 moles of CaCO3 will give 0.09 moles of CO2


Now according to the mole concept,


1 mole of CO2 will occupy 22.4 L by volume.


So, 0.09 moles of CO2 will occupy 22.4 × 0.09 L by volume


So total volume occupied = 2.016 L
