I gotta a project on 1st hand investigation but i am not quite familiar with the experiment report.
I have to test solubilities of three groups of substances in water (ionic:NaCl,soluble molecular:sucrose; insoluble molecular: cooking oil)btw, all the stuff u uesd must be commonly household materials.
I think mass should be the same for all the samples, right? but how to control the mass of these samples if u only allow to use normal household equipment?
and what is the independent variable and dependent variable respectively in this experiment?

thanx a lot
