20 "litre" of air containing CO_(2) at STP passed through 100 mL of 0.12 N solution of Ca(OH)_(2). The filtrate obtained after the reaction required 50 mL of a solution of HCl of specific gravity 1.25 g mL^(-1) containing 0.35% by weight of acid. Find the amount of CO_(2) present in the volume of air as well as thepercentage by volume of CO_(2) in air.
