If nineteen and one hundredth percent of the volume of gas in a storage tank is oxygen, then all the other gases in the tank make up what percent of the volume of the gases in the tank?

If 19.01% of the volume of the gases in the tank is oxygen, then the remaining 80.99% must be other gases in the tank. Therefore, all the other gases in the tank make up 80.99% of the volume of the gases in the tank.

To find out what percent the other gases make up in the tank, we need to subtract the percentage of oxygen from 100%.

Step 1: Subtract the percentage of oxygen from 100%:
100% - 19.01% = 80.99%

Step 2: The other gases in the tank make up approximately 80.99% of the volume of the gases in the tank.

Therefore, all the other gases in the tank make up approximately 80.99% of the volume of the gases in the tank.
