1 gallon to how many propels pack (to go packs)?

Question

I have some propel packs and I dont use them and want to put them in a gallon of water. They read 16.9 oz(of water).

Answer 1

1pt of water = 568∙181818...g of water.
8pt of water = 4545∙454545...g of water. (But 8pt = 1 Gallon).
1 Gallon = 4545∙4545454....g or water.

16 oz = 454∙454545....g of water.
1 oz = 28∙4090909....g of water.
16∙9 oz = 480∙113 6364....g of water.

Now, how many 16∙9 oz fit into 1 Gallon?
4545∙4545454 / 480∙113 6364 = 9∙467 455 621 packs.
4545∙4545454 / 480∙113 6364 ≈ 9∙5 packs.
