Chemysrylation

The links don't tell me how to calculate it properly. Can you calculate 1 example for this, please? Propionic acid can have 10ml/m³ in the air. What's the corresponding concentration for this in a solution as a liquid (under normal air pressure (760 mm Hg) and temperature (25 °C) ?

What data banks do they use when they mix perfumes and use acids so they know how high they can go in their concentrations? What data banks do they use when they make prank sprays that smell bad? Is there anybody here who knows anything about it or who else could I ask? Grateful for any hints because I am currently clueless. ❔❓

I feel sorry for your apprehensions hoping that people who try to block communication are not the only ones to contribute here. Some of the acids may be classified as organic, too. It won't matter. Neither am I a pharmaceutic. Just curious and a friend of knowledge...

I'd like to know how much I'd have to dilute the following acids in a given solvent so that their vapors/malodors could simply be inhaled without causing any harm to one's health: - butyric acid - isovaleric acid - propionic acid I am not interested in any ppm values or thelike, but only in the values for the maximal possible concentrations of the acids in solutions so that they generally can't cause any harm any more if you inhale them (e. g. if the solution is then sprayed into the air or on a piece of cloth to be smelled...). How do I get to know these values anyways? I couldn't find anything on this online. Possible applications for this are manifold: creating prank sprays, scent generators, tests with sniffing sticks...
