I don't know what mine weighs but it's pretty simple. Emergency blanket, 1 roll medical tape, 5 small strip band aids, 5 medium strip band aids, 3 4x4 gauze, small vial super glue, ibuprofen.
Ironically I used to carry a lot more in a first aid kit until getting on the street as a firefighter. Most issues can be fixed with some gauze, water, and medical tape/coban. If it requires more than that your hiking trip is most certainly over and you've got bigger issues. Hopefully qualified help is on the way or else your likely screwed.
Like anything else it boils down to packing for what's likely and packing for your fears. If I packed for "what ifs" I'd have at least a 20 lb med kit with Sam splints, coban, gauze, airways, bvm etc... But we all know the likelihood of having to ventilate someone on the trail is practically zilch.
Carry the basics, don't go overboard.
