Solving for mass of a solute given ppm and volume?

  1. Mar 16, 2016 #1
    The question is: A solution contains 23ppm of dissolved O2 in 242.0066 mL of solution. What is the mass of the oxygen.

    Formula: ppm=(grams of solute/grams of solution)*1,000,000

    I tried plugging stuff in but it wasn't working out what so ever.

    I just don't know how to do these when given so little information. Thanks in advance if you can help.

    The solution is NOT water.

    Formula calls for the mass of the solution. You are give volume. You either have enough information to do the conversion, or not - hard to say not knowing the context.
