There isn't one - each quest is different for each level. Doing the epic quest (lvl70+) - rescuing Undercity gives over 20k (and each of the sub-quests leading to the main gave between 5k and 20k) Several quests in Icecrown- The Ebon Blade rep quests in Joturheim etc have given between 15k and 20k to my level 75 DK. The lower your level when you do the quest the more exp you get EXCEPT when the quest goes gray in your log - then you only get money for it.
This would depend on your level and the level of the mob (creature) you are fighting. If a mob is too low, then you will not get any experience what so ever. However, if a creature is too high for you to kill, you will not get any experience because the creature will probably have killed you.
It is always best to take out mobs that are your level (yellow) as they will be giving the most experience per hour. Orange mobs may give better experience, but take longer to kill.
I think it is the portico quest in celestia which gives you around 21,000 experience, and is a dungeon.
If you receive a complete set of gold,xp,and drop items you must enhance the drop item or if it is a quest item turn it in to the NPC that needs it or if its only gold and xp there's nothing you need to do with them.
hi its easy kill stuff.
Temple of Ikov give a decent amount of ranging experience.
Do swept away quest, its 10x exp for your skill level so if u have 50 strength and u use on of the ten exp lamps you will receive 500xp in that skill lvl and so A quest that gives you two 10,000 xp lamps is called "One Small Favour", but this quest is quite long. SliceGallary,
There is a quest called "The Digsite" .It gives you at least 15,000 exp. Its an intermediate kind of quest and its a lot of fun http://runescape.wikia.com/wiki/The_Dig_Site
Black Ops.
Quest grinding is just doing all the quests that you come across. This is different that mob grinding in that you get more XP (experience) from doing quests because you get the added XP from the quest AND the xp from killing the mobs.
for a non-member that's at least lvl 48 (to be safe) the dragon slayers quest (and you need 33 quest pts i think).18,000 strenghth xp and 18,000 attack xp.
You battle beasts.
Play Demolition, it gives you the most xp.
none, they all suck
Ghosts have the highest potential for most xp considering there can be multiple arches in 1 mob but best consistent xp I say is minotot
