How quickly salt dissolves in water is affected by:
1) Temperature -Higher temp means particles have more kinetic energy, so more collisions occur, and dissolving occurs faster.
2) Concentration - the more salt particles involved, the harder it is for water molcules to surround each ion (sodium and chloride). Thus the rate of dissoving slows down.
3) Particle size/ surface area - a lump of salt takes longer to dissolve than tiny crystals because water molecules are able to interace with ions in the tiny crystals easier. Mixing is a means of increasing the surface area of the salt exposed to water molecules.
4) Pressure only applies to gases.
5) It won't dissolve at all in oil (extreme example of an organic/ covalent substance) so, I guess here the solvent won't affect the rate

i've got faith the final 2 questions are approximately osmosis, not solubility. a million) The dissolved CO2 is shifting from a intense concentration to low. that's the only question i'm able to respond to with certainty. i'm guessing with regard to the 0.33 that by way of fact the temperature has extra desirable, extra gasses like N2 and CO2 have dissolved in the water.

Dissolved salts occupy the inter molecular space.
The factors could be 1-purity of water, purer the better for solubility. 2- If you raise he temperature more salt will dissolve because inter molecular space will increase.

Remember "rate" is a kinetic term, it does not refer to the final equilibrium.
Most important factors are likely to be temperature, particle size, rate of agitation, volume of water.

how pure the water is, meaning how many metals and other impurities cloud the water
how much salt you have, or the concentration
pressure
temperature
