How does alcohol content work? (NSFW?)

Question

Let’s say you got a 0.5L bottle of alcohol with 40% alcohol in it. If you pour 100ML from that bottle in to a glass does that also contain 40% alcohol?

In: 0

Answer 1

…yes. No matter the quantity of liquid you have from that bottle, 40% of it will be alcohol. In your example, there would be 40 ml of pure alcohol within those 100 ml.
