      1. Determine the mass of the water.
      2. Determine the moles of the salt
      3. Determine the moles of the water.
      4. Calculate the ratio.

      Since I can't see what the problem is, I'm going to calculate this out ...

      O.k., that works. If you have trouble, post and I'll show you the calculations.


      Why do they want us to believe Conspiracy Theories?
