Archetype Sub-90 Dry-Wipe Invariant (Solubility Curves (g per 100 g Water), Recrystallisation Mass & Paper/TLC Chromatography R_f): Check the exact wording on the mass given: if given M grams of WATER, Precipitate = (M/100)*(S_hot - S_cold). If given M grams of SATURATED SOLUTION at T_hot, Precipitate = M * (S_hot - S_cold) / (100 + S_hot).
