Question

the molarity of a solution M.To decrease the molarity of this solution to M/2,THEN​

Answer 1

Answer:

Decrease moles of solute by 2 times the initial mole or increase the volume of solvent by 2 times.

Explanation:

• molarity directly depends on number of moles and depends inversely on volume.

Answer 2

Answer: The molarity of a solution is M. Molarity of this solution decreases to M/2 by:-

1. Decreasing mass of solute by 1/2.
2. Increasing Volume of solution by 2.

Explanation:

As Molarity = $\frac{mass of solute}{Molar mass of solute * Volume of solution}$
