1.8 percent of 2 fluid ounces is how many milligrams?   (05/09/2017, 9:03 PM)

I've got a 2 oz. bottle of e-cigarette liquid that says it's 1.8% nicotine. Most of these bottles note how many milligrams nicotine are are in them regardless of how many ounces are in the bottle. For instance, I bought a bottle that says it contains 24 milligrams nicotine. How many milligrams are in a 2 oz. bottle that says it is 1.8% nicotine?
