Diluting 1.0 mL of a 1.0 M solution to 1,000 mL results in a solution that is 0.001 M. Repeating this 1,000-fold dilution process five more times results in a concentration of __________

Question

Quizplus · Accepted Answer

Each 1,000-fold dilution reduces the concentration by a factor of 1,000 (10^3). After six such dilutions, the concentration is reduced by a factor of (10^3)^6 = 10^18, resulting in a final concentration of 1.0 * 10^-18 M.
