Weight = mass x gravity
You can't. Work is (force) times (distance), so you have to know something about the force. Just knowing the mass doesn't tell you anything about the force ... unless there's actually something else about the mass that you've overlooked.
Because you have to do work on the pair ... add work to them ...in order to separate them.
Weight is mass times acceleration due to gravity.
You cannot. You do not have the necessary information.
