In a cylinder with air, the volume of which is 140m ^ 2, oxygen occupies 29.4 ^ 2.

In a cylinder with air, the volume of which is 140m ^ 2, oxygen occupies 29.4 ^ 2. What is the percentage of oxygen in an air cylinder?

To determine the percentage of oxygen in a cylinder, the volume of this oxygen must be divided by the total volume of air in the cylinder, and then multiplied by 100%.

In our case, we get:

29.4 m ^ 3/140 m ^ 3 * 100% = 21%

Thus, the oxygen content in the cylinder is 21%.
