for the density of water, i got 1.25 g/cm3 ... and i dont know if anythings dissolved in there and i cant check it. Would density make a difference if say salt was dissolved in it?

Usually. If a solid solute is dissolved in water, the mass of the solution usually increases faster than the volume of the solution.
Since density is the mass per unit volume, this means that the density would increase. Pure water is about 1.00 g/cm^3.

Yes.
When I was in school, back when dinosaurs roamed the earth, I used a process of gradually increasing the density of a water bath with dissolved salts to separate midden samples by SG, and float the organics out for analysis.
Ever seen pictures of people floating in the Dead Sea?

density of water (or any liquid) definitely does change if there is a dissolved solid present.
its really intuitive density is defined as grams per cubic cm, if there is a dissolved solid the solution will have more mass per volume

Yes. It will decrease. Becoz density is inversely proportional to Volume.

Yes, that's why it's easier to float in the great salt lake than it is to float in your pool water at home.

absolutely...pure waters specific gravity is 1.0000 gr/cm3 so you definitely have something in there, but how much of what is not something you can determine without quantitative analysis.

Yes, you are weighing water and other substances together.
