The percentage of alcohol that is absorbed through the small intestines is 80%. The remaining 20% of alcohol consumed is absorbed through the stomach.
The stomach does not absorb anything. In fact, the stomach secretes a great amount of mucus to prevent the acid in the stomach from damaging the stomach walls. If the mucus were thin enough to allow absorption of chemicals, then you would also have an ulcer from acid damage.

Ibuprofen is mostly absorbed in the duodenum (small intestine). It cannot be absorbed through the lining of the stomach due to its low solubility in water and the low pH of stomach acid (since ibuprofen dissolves in water better at higher pH's).
liquids that are isotonic (about a 1% solution) [except for alcohol which can be absorbed directly through the stomach.]
