Question

The mass concentration of a potassium chloride solution is 60 g/dm3.What is the mass of potassium chloride in 25 cm3 of this solution?

Answer 1

I'm pretty sure its 8.9 g DM -3?

Answer 2

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.
