Hi, Just have follow up questions to the previous questions asked dating Feb. 02, 2013

1. So the overall idea is that dissociation decreases molar mass and association does the opposite when a solute dissolves in a solvent. (How do you identify if either reaction occurs? Just wondering.)

2.So in this case, that a small amount of your unknown failed to dissolve in the t-butanol, it would effect the molar mass, just depending on the mass of both substances?

Thanks for your time

    1. Dissociation decreases the IONIC mass (the molecule is gone) and association increases the molar mass. Experience is probably the best indicator of which is going on.

    2. I've forgotten the t-butanol part of the question.
