Put all of them in the scale, and start removing one by one, first it will be 501 then 401 or 400, once the indicator doesn't show the 01 then if means that the one you removed is the one which weight 101, you said the scale can weight only one time, so removing them from the scale doesn't break the rule I guess, maybe I'm wrong, but that's all what I could think of for right now.
