Final answer:
Solution B likely has a higher concentration of purple particles compared to Solution A.
Step-by-step explanation:
Solution B likely is the more concentrated solution because osmolality measures the moles of solute per kilogram of solvent. When comparing the concentrations of two solutions, it is important to consider the ratio of solute particles to solvent particles. Solution B, with a larger volume of 40 mL, is likely to have a higher concentration of purple particles compared to Solution A, which has a volume of 30 mL.
