The content of carbon monoxide in the exhaust gases of Zhiguli vehicles should not exceed 4.5% by volume. Does the engine operating mode correspond to the specified norm if, when passing 25 liters of exhaust gases (containing CO2 by volume twice as much as CO) through 18.5 ml of a 10% NaOH solution (density 1.1089 g / cm3), the solution was completely saturated ?
