How much does 750ml bottle of whiskey weigh?

It's impossible to give an exact weight for a 750ml bottle of whiskey without knowing more information. Here's why:

* Whiskey Density: Different whiskeys have different densities due to varying alcohol content, age, and ingredients.

* Bottle Weight: The weight of the glass bottle itself varies depending on the brand and style.

Here's a rough estimate:

* Whiskey: Assuming an average density of about 0.92 g/ml (typical for 40% ABV whiskey), 750ml of whiskey would weigh approximately 690 grams.

* Bottle: A standard glass bottle might weigh around 300-400 grams.

Therefore, a 750ml bottle of whiskey would likely weigh somewhere between 990-1090 grams (approximately 2.2-2.4 pounds).

To get a more precise weight, you'd need to:

* Know the specific gravity of the whiskey. This can be found on the bottle's label or online.

* Weigh the empty bottle.
