4.0 g of sodium hydroxide NaOH was dissolved in sufficient water to make up 125 mL of solution.
A) Find the concentration of the solution.
B) What mass of sodium hydroxide could be obtained by heating a 20 mL sample of this solution to dryness?
C) If 30 mL of the solution were mixed with sufficient water to produce 480 mL of a more dilute solution, what would be the concentration of the dilute solution?
D) If 200 mL of the more dilute solution were then mixed with 100 mL of the more concentrated solution, what would be the concentration of the mixed solution?
