There was an irregular shaped glass bottle with strong acid in it. There are only two scale marks on the bottle, the higher one is 10 liters, and the lower one is 5 liters.
At present, the scale of strong acid in the bottle is lower than 10 liters, but higher than 5 liters. Is there any simple way to accurately pour 5 liters of strong acid out of the bottle? (because strong acid is very volatile, it cannot be poured out of the bottle.)
