To compute the concentration, we use percent weight / weight of the solution, given by: mass of solute / mass of solution × 100%. The first concentration is (5 g salt / 15 grams solution) × 100% = 33.33%. The second concentration is (18 g salt /108 g solution) × 100% = 16.67%. Therefore, the first solution is more concentrated.
