What is the concentration of a solution prepared by placing 20. ml of 0.12 m k2s in a graduated cylinder and pouring water until you reach the 100.0 ml mark (the final volume after mixing the solution with water is 100.0 ml).

0.024 M

Explanation:

According to the neutralization law,

where,

= molarity of stock solution = 0.12 M

= volume of stock solution = 20.0 ml

= molarity of diluted solution = ? M

= volume of diluted solution = 100.0 ml

Putting in the values we get:

Therefore, the concentration of the resulting solution is 0.024 M.
