I am still having trouble with this question It says What is the molarity of a solution containing 18.0g of KCl in 262mL of KCl solution? When I calculated it I got .92154 m. I had changed 18 g into moles and 262 ml into liters and then divided the moles into liters. I was wondering where I went wrong because that isn't the answer in the book.

    The correct answer is 0.92154 using 74.551 for the molar mass of KCl. Rounded to 3 s.f. that is 0.922 and note that is M and not m. M stands for molarity, m stands for molality.
    What's the answer in the book?
