To solve this problem, we can use the dilution formula:C1 × V1 = C2 × V2Where:- C1 is the initial concentration of the solution (9.0 M)- V1 is the initial volume of the solution (450 mL)- C2 is the final concentration of the solution (0.075 M)- V2 is the final volume of the solution (unknown)Rearranging the formula to solve for V2:V2 = (C1 × V1) / C2Substituting the given values:V2 = (9.0 M × 450 mL) / 0.075 MV2 = 5400 mLTherefore, the final volume of the 0.075 M NaCl solution that can be made by diluting 450 mL of 9.0 M NaCl is 5400 mL.To convert the final volume to liters, we can divide by 1000:V2 = 5400 mL / 1000 = 5.4 LSo, the final volume in liters is 5.4 L.
