A patient uses an oxygen tank to breathe. At the beginning of your shift, the gauge on the tank shows the internal gas pressure to be 250 psi. At the end of your shift you check the tank again and find the pressure to be 25 psi (psi stands for pounds per square inch; it is another unit of pressure). The number of molecules is directly proportional to the pressure of the system. What proportion of the gas molecules was used?
