200 ml of water is added to 500 ml of 0.2 M solution. What is the molarity of this diluted solution?

Options

  1. A0.7093 M
  2. B0.1428 M
  3. C0.4005 M
  4. D0.2897 M

Correct answer

B. 0.1428 M

Step-by-step solution

No. of millimoles = 500 × 0.2 = 100 Total volume in mililitre = 500 + 200 = 700 Thus, molarity of diluted Solution: = 100 700 = 0.1428 M
