3174 x 100 grams = 31.74 grams NaClO2
.3174 x 9 ounces = 2.8566 ounces H2O

These figures are correct. You need 2.8566 ounces of H2O and 31.74 grams of NaClO2 to make exactly 4 ounce of Miracle-Mineral-Supplement .
To figure this out.
9/12.6 = x/4
(9/12.6)4 = x
x = 2.857 ounces of water
Now plug that into the original formula
(100/9)( 2.8571) = x
x = 31.74556 grams of Sodium Chlorite.
After doing a little math on chapter 17 of Book 2 it seems as though Jim Humbles recipe makes a little extra Miracle-Mineral-Supplement than what is required to fill the 4 ounce bottles. Plus he recommends filling the bottles up all the way which is a not a good idea. Fluid does not compress and tends to build up pressure very quickly. A little air at the top will prevent this from happening.
