What is a 500 Bottle of liquor?

Here's what you need to know:

* 500ml is a common size for liquor bottles.

* It's equivalent to 16.9 fluid ounces, which is slightly less than a standard 750ml bottle.

* These bottles are often referred to as "fifths" because they contain one-fifth of a gallon (which is 128 fluid ounces).

However, it's also possible that you meant something else entirely. To be more specific, please tell me:

* What kind of liquor are you interested in? (e.g., whiskey, vodka, tequila)

* What is the context? (e.g., are you buying a bottle, looking for a specific size, or trying to understand a label?)

Once you provide more information, I can give you a more precise answer.
