To determine which solution exhibits the greatest concentration of salt, we would need to know the specific concentrations of each solution. If the table you mentioned listed the concentrations of each solution (e.g., in grams per liter or molarity), you could identify the one with the highest concentration.
Without that information, I cannot accurately answer your question. If you could provide the concentration values for Solutions A, B, C, and D, I'd be happy to help you find the one with the greatest concentration of salt!
