1 Answer

Answer :

(1) 4% Explanation: Carbon dioxide exists in Earth's atmosphere in this state, as a trace gas at a concentration of 0.039 per cent by volume. The air we breathe in contains about 0.04% carbon dioxide. The air we breathe out contains about 4% carbon dioxide. In other words, exhaled air contains about 100 times the concentration of carbon dioxide that inhaled air does.
