Why are density and solubility size independent properties of matter?
Dependant and independant properties refer to wether or not they change depending on how much of it you have. Dependent properties will change based on amount of stuff. Some examples of dependent properties are mass (if you have more of it it will weigh more) and volume (if you have more of it it will take up more space). Independent properties will not change based on amount. As you mentioned density, if you have 1 gram of something it will have the same density as 1000 grams of the same thing which will have the same density as 10000000 kilograms of the same thing. Similar to solubility, solubility refers to how much of something will disolve in something else (normally on a % basis or mass per volume). So no matter how much of the substance you have, you can only disolve x grams per liter.
