You have 363 ml of a 1.25m potassium chloride solution, but you need to make a 0.50m potassium chloride solution. how many millimeters of water must you add to the original 1.25m solution to make the 0.50m potassium chloride solution? note: assume the volumes are additive. of water need to be added

- 544.5 mL of water need to be added.

Solution:- It is a dilution problem. The equation used for solving this type of problems is:

where, is initial molarity and   is the molarity after dilution. Similarly,   is the volume before dilution and   is the volume after dilution.

Let's plug in the values in the equation:

Volume of water added = 907.5mL - 363mL  = 544.5 mL

So, 544.5 mL of water are need to be added to the original solution for dilution.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

where are the choice options?
