What is the Mean Free Path of water in it's liquid state?

Just wondering how far an electron could travel in water before a collision?

The mean free path has more significance when you are talking about a collection of free particles, i.e. a gas, an not so much a liquid. In a liquid, the molecules are loosely bound, so they are constant contact of each other. The mean free path of a liquid would thererfore be the distance between neighboring molecules. You could treat a liquid as a gas and do a kinematic mean-free-path analysis of it, but I don't think it would be very accurate.
