Question

Which solution has the greater concentration?

A. 0.500 mole LiCl dissolved in 250 ml solution

B. 0.250 mole LiCl dissolved in 250 ml of solution

C. Both the same

Answer 1

The higher concentrated solution is 0.250 mole LiCl dissolved in 250 ml of solution

( B).0.250mole of LiCl diluted in 250ml solution

Step-by-step explanation:

Procedure to find the intensity of the solution:

To find the intensity of the solution, we have to use the following formula

M1V1=M2V2

250mL of a 0.500 M aqueous solution of LiCl is diluted with water

`M1V1=(250) * (0.500)=125M`

250 ml of a 0.250M aqueous solution of LiCl is diluted with water

`M2V2=(250) * (0.250)=62.5M`

Thus the PH level of a solution increases from ascending order, Therefore the Solution with 62.5M is a higher concentration than that of the solution with 125M.
