Question
Four salt solutions are created using different amounts of salt and water, as shown.Solution Salt(tablespoon) Water(mL)P 2 200Q 2 100R 1 200S 1 100Which solution has the highest concentration, and why?ResponsesSolution P; it has more salt and water compared to the other solutions.Solution P; it has more salt and water compared to the other solutions.Solution Q; it has more salt with a smaller amount of water compared to the other solutions.Solution Q; it has more salt with a smaller amount of water compared to the other solutions.Solution R; it has less salt with a larger amount of water compared to the other solutions.Solution R; it has less salt with a larger amount of water compared to the other solutions.Solution S; it has less salt and water compared to the other solutions.
Solution
The solution with the highest concentration is Solution Q. Concentration is determined by the amount of solute (in this case, salt) in a given amount of solvent (in this case, water). Even though Solution P has the same amount of salt as Solution Q, the amount of water in Solution Q is half that of Solution P, making the concentration of salt in Solution Q higher. The same logic applies when comparing Solutions R and S. Therefore, Solution Q has the highest concentration of salt.
