If 17.8 grams of koh dissolve in enough water to make a 198-gram solution, what is the concentration in percent by mass? . a. 8.25% koh. b. 8.99% koh. c. 10.9% koh. d. 11.1% koh

The correct answer is option B.

Explanation:

Mass of potassium hydroxide =17.8 g

Mass of the solution = 198 g

Concentration in percent by mass:

So, the  concentration in percent by mass of KOH will be:

The closest answer to our answer is option B. Hence, the correct answer is option B.
