2 kinds of measurable properties of matter -

Some properties are entity-dependent while some are entity-independent. Weight, volume, etc. are entity-independent. So naturally all entities have them. So what is in the property like weight, that it doesn't matter what substance you are considering? (or volume too). Is this the inspiration to the idea that all different matter is ultimately made up of something of the same kind, and which again has weight and volume and thus is matter again (having mass and volume) - (molecules)? Because then only can mass and volume be independent of the substance you are considering - everything has to be made up of the same kind of thing (molecules). Number of keys (keyboard, piano), data storage capacity (pen drive), speed of rotation (earth), softness/hardness, surface area etc. are entity-dependent. 2 kinds of non-measurable/qualitative properties of matter - EI - color, reactivity etc. ED - behavior, looks, friendliness
