The density of the mixed gas composed of carbon dioxide, hydrogen and carbon monoxide is the same as that of nitrogen at the same temperature and pressure. Then the volume ratio of carbon dioxide, hydrogen and carbon monoxide in the mixed gas is () A. 29:8:13 B. 22:1:14 C. 13:8:29 D. 26:16:57

The density of the mixed gas composed of carbon dioxide, hydrogen and carbon monoxide is the same as that of nitrogen at the same temperature and pressure. It can be seen that the average relative molecular weight of the mixed gas is equal to the relative molecular weight of nitrogen, which is 28, while the relative molecular weight of carbon monoxide is also 28, so the average relative molecular weight of carbon dioxide and hydrogen is 28
