Grade 12 Stoichiometry

If W2 is the weight of solute in grams or Kgs and W1 is the weight of solvent in grams or kgs, then what is the concentration of such a solution in parts per million (ppm)?
  1. Parts per million (ppm) = W2W1+W2×106
  2. Parts per million (ppm) = [W1+W2W1]×10-3
  3. Parts per million (ppm) = W1W1+W2+102
  4. parts per million (ppm) = W2W1-W2×105
