Homework Help: Osmolarity Question

  1. Aug 8, 2013 #1
    1. The problem statement, all variables and given/known data

    I tried to solve this question, but I'm not sure if my answer is correct.

    What is the osmolarity of a 0.500 liter solution containing 132g of KNO3?

    2. Relevant equations


    3. The attempt at a solution

    1.306 mol/0.500 L solution x 2 mol ions/1 mol KNO3 = 5.224

    What is the volume of solution? You seem to have assumed it to be 1L.

    It's 0.500L. I've reworked the equation, but I'm not sure how to proceed.
