...amounts at present to about 1,100,000 tons (1910). In the atmosphere, which consists approximately of 21 per cent. oxygen and 79 per cent. nitrogen by volume, there is an inexhaustible store of nitrogen. It has been calculated that the atmosphere contains about... | |

...each for complete combustion, and 1 cu. ft. of CO will produce 1 cu. ft. of CO2. Since air is composed of 21 per cent oxygen and 79 per cent nitrogen by volume, the ratio of the nitrogen and of the air to the oxygen is 79/21 = 3.76 and 100/21 = 4.76, respectively,... | |
