How much is one fifth of alcohol?

You're asking about alcohol content, and it's important to understand that "one fifth" refers to a volume, not a specific percentage of alcohol.

Here's what you need to know:

* "One fifth" is a common size for liquor bottles, containing 750ml (25.4 ounces).

* Alcohol content is measured as a percentage of alcohol by volume (ABV). This percentage varies widely depending on the type of alcoholic beverage.

To find out how much alcohol is in "one fifth," you need to know the ABV of the specific drink. For example:

* A bottle of wine with 12% ABV: 750ml x 0.12 = 90ml of pure alcohol.

* A bottle of whiskey with 40% ABV: 750ml x 0.40 = 300ml of pure alcohol.

It's important to be aware of how much alcohol you're consuming, as it can affect your health and safety.
