The weight of something is the amount of energy you need to apply to stop it being influenced by the forces acting against it, in actuality - gravity. Atoms have mass. Mass is the density of molecules per area (e.g. of the molecular structure of a cake). In relation, gravity on Earth is a multiplier by 1 (e.g. 1kg of Newton Metres of force applied to stop the cake falling to the ground when you hold it). If you take what you bake into space (far enough away from Earth), it would have less force acting upon it... and so would be weightless!
