Mass and Volume?

Question

Well i am back for some more questions.
I figured out that there is a relationship between mass and volume only when the density(object) is the same.

So now, in my experiment i have to use sample aluminum.
It is just like a round water droplet and NOT the log cylindrical samples.

Ok so my question is:

Lets say i start out with 5 samples i record the data. THEN i add 5 more samples. Record the data. And so on. Will this still show that there is a realtionship between mass and volume. A proportional relatiosnhiop?

Answer 1

it will work, because of the density triangle. this triangle shows the formulas between the density and mass and also volume. this will w=be the relationship that you will find. (by the way i have re-answered your other question)

Answer 2

Density:
D = m/v

In your case you're playing with uniform material with a known, constant density. So
m = D*v
where the density, D, is a constant and m and v are variables. So v is proportional to m and D is the constant of proportionality. In other words, yes to your question.
