What is the correct notation for computing the partial pressure of gases, is it more correct to use brackets versus parenthesis when doing a problem of this sort?

Brackets denote concentration and partial pressure is not measured by concentration so I would assume that parentheses would be best when you are dealing with partial pressures.

Yes, my TA usually uses parenthesis or nothing at all when doing a problem with partial pressure. With concentration, brackets are always used.

So partial pressure is parentheses and concentration is brackets?

Brackets would denote concentration. Therefore, it would be a better idea to use either parenthesis or nothing at all for partial pressure to minimize confusion.

Brackets represent concentration, so I've seen them used in Kc problems, while I've seen both parentheses and nothing used with equilibrium problems concerning partial pressure
