Problem- Suppose you dissolve a commercial aspirin tablet in enough water to create 1000 mL of solution (Solution A). You then remove 24.9 mL of this solution and dilute it to 656.0 mL to create Solution B. You then determine that Solution B has a molarity of 0.00042. What was the concentration of Solution A?
