How many ounces of iodine worth 80 cents?

To answer “how many ounces of iodine worth 80 cents,” you need the iodine’s price per unit (for example, cents per ounce or dollars per ounce). With only “80 cents” and no per-ounce price, there isn’t enough information to calculate ounces.

If you tell me the price (e.g., “iodine is $X per ounce” or “$Y per bottle/oz”), I can compute the exact ounce amount.
