Homework Equations

The Attempt at a Solution

I thought the best way of measuring the density would be to fill a tube which you know the mass of with the liquid, then subtract the original mass of the tube and it would give you the density of the liquid. Am I correct? Please help me, thank you!

You're right so far. Make sure that you know the volume that the water takes up.
