Question
Miranda makes four different solutions by mixing salt and water as shown in the table below.Solution Weight of Salt Volume of Water1 5 g 50 mL2 5 g 100 mL3 5 g 150 mL4 5 g 200 mLWhich solution has the lowest concentration? A. solution 3 B. solution 1 C. solution 4 D. solution 2
Solution
The concentration of a solution is determined by the ratio of the amount of solute (in this case, salt) to the amount of solvent (in this case, water). The more solvent there is in relation to the solute, the lower the concentration of the solution.
In this case, all four solutions have the same amount of solute (5g of salt), but different amounts of solvent (50mL, 100mL, 150mL, and 200mL of water). Therefore, the solution with the most water (and thus the lowest concentration of salt) is solution 4.
So, the answer is C. solution 4.
