All matter has mass and occupies space. Volume is a measure of how much space an object occupies. ... "Weight", on the other hand, depends on how strongly gravity pulls on an object.

Is everything which is matter have weight?

Matter is anything that has real mass and occupies volume in space. Weight is a quantity that equates to the product of an object's mass and the gravitational field strength acting on the object.

Does matter have weight yes or no?

In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity. ... Similarly, a balloon has mass but may appear to have no weight or even negative weight, due to buoyancy in air.
