How to convert 57 liter Oxygen per hour to ppm?

I don't know what liters per hour stands for, but by intuition I would say you could convert Litres into number of parts (molecules) by the gas equation and the hour to minutes... I'm not sure though, so better wait for someone else to answer.

By the way, could you explain me where do we use the notation "Liters per hour"? I would really like to know.

You can't convert liters per hour to ppm. One is speed, other is concentration, you can't convert one to other just like you can't convert mph to miles.

worse yet 'liters' isn't even a concentration, its an volume or amount.

No idea what you refer to, I guess you just didn't understand a word of my post.

How to convert 57 liter Oxygen per hour to ppm?

If oxygen is pressured into a liquid at ~ 65*F, and the only factor known is 57 liter ( 1liter X 1,000 = ml) per hour, how do we calculate the ppm O2 per hour ?

[Borek]

We don't. Question still doesn't make sense. ppm of what in what?

It still doesn't make a lot of sense, but I think I know where the question is going. Is this what you mean?

If 57 liters of oxygen is dissolved per hour into a solvent at constant pressure at 65 degrees Farenheit, find the change of concentration of O2 in ppm per hour. (It can't be answered without volume of the solvent.)
