Air containing carbon dioxide at a concentration of 0.05% is pumped into a room with a volume of 90000 m3 at a rate of 9000 m3 per minute. After the said air mixes homogeneously with the air in the room, it is pumped out of the room at the rate of 9000 m3 per minute. The initial air in the room contains carbon dioxide in a concentration of 0.2%. What is the % carbon dioxide concentration in the room after 20 minutes? Please choose one: a. 0.050% b. 0.057% c. 0.053% D. 0.070% to. 0.060%
