Answer: 8.9 g DM -3

Explanation: Your goal here is to convert the concentration of chloride anions from moles per cubic decimeter to grams per cubic decimeter.

Now, you know that potassium chloride is soluble in water, so it will dissociate completely in aqueous solution to produce potassium cations and chloride anions.
