Question
What is the concentration (M) of KCl in a solution made by mixing 25.0 mL of 0.200 M KCl with 100 mL of 0.200 M KCl?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Both solutions have the same concentration (0.200 M). Mixing them does not change the concentration; it remains 0.200 M.
Hint
Mixing two identical concentrations yields the same concentration.
