INTERPRETATION OF RESULTS

[SofiaHerrera]

Good day
As a result of a speciation simulation that I carried out in the program, a table of percentages of the species obtained in Phreeplot is obtained. Are these percentages molar or mass?
I have read the manual and cannot find an answer to this. (I attached a picture).
I appreciate your attention and collaboration.

I'm sure the program would use moles in the calculation, but moles, molality, or mass would still give the same percentages.
