This is from TBR Gen Chem 2, Solubility section. The passage is called "Solubility Experiment" and I believe it's in the older edition of TBR as well.
Two compounds are given, compound A and B. Both are partially dissolved in water and compound A has higher molar solubility. So on molar basis, compound A dissolves better in water.
Does this also mean that compound A has a higher gram solubility? I am assuming that the answer depends on the molecular weight of each compound and how much difference there is for molar solubility. However, generally speaking, molar solubility difference is in the order of a few magnitudes, so molar mass difference is usually not large enough make the reverse statement true.
Also, TBR states that gram solubility is temperature dependent, but it does not mention anything related to temperature for molar solubility. Why is this? I would sincerely appreciate your response. Thank you!
