Question

The volume of water that should be added to 20 ml of 0.1 M H2SO4 solution to make it millimolar solution is​

Answer 1

Given:

Initial molarity, M1 = 0.1 M

Initial volume, V1 = 20 ml

The final solution is millimolar.

⇒ Final molarity, M2 = 0.001 M

To Find:

The volume of water that should be added.

Calculation:

- Using the molarity equation, we get:

M1 × V1 = M2 × V2

⇒ 0.1 × 20 = 0.001 × V2

⇒ V2 = 2000 ml

- The volume of water added = V2 - V1

⇒ V = 2000 - 20

⇒ V = 1980 ml

- So, 1980 ml of water should be added to 20 ml of 0.1 M H2SO4 solution to make it a millimolar solution.
