On average a -ounce can of beer 5-ounce glass wine and an ounce-and-a-half whiskey all contain about the same amount alcohol.?

You're close, but the amounts of alcohol in those drinks are not exactly the same. Here's a breakdown:

* 12-ounce can of beer: Typically contains around 5% alcohol by volume (ABV). This means a 12-ounce can has about 0.6 ounces of pure alcohol.

* 5-ounce glass of wine: Usually has 12% ABV, so it contains about 0.6 ounces of pure alcohol.

* 1.5-ounce shot of whiskey: Generally has 40% ABV, which translates to about 0.6 ounces of pure alcohol.

So, yes, a 12-ounce beer, a 5-ounce glass of wine, and a 1.5-ounce shot of whiskey all contain roughly the same amount of alcohol (around 0.6 ounces).

However, it's important to remember that the effect of alcohol can vary depending on factors like body weight, metabolism, and how quickly you consume the drinks.
