1. write a step-by-step process for finding the density of an unknown liquid. list the laboratory equipment needed for each step.
thanks!!

density equals mass over volume. In order to find it a procedure known as density determinant is used and the laboratory equipment is flask, thermoemter, and measureing cup.

All you need is an accurate lanoratory scales and a graduated cylinder.
1) Weigh the empty graduated cylinder. Record the mass.
2) Put any volume of the liquid you wish in the cylinder. Record the volume.
3. Weigh the cylinder with the measured volume of liquid. Record the mass.
4. Subtract #1 from #3. That is the mass of the liquid.
5. Divide the mass from #4 by the volume recorded in #2, and that is you density.

Weigh an empty graduated cylinder.
Fill the cylinder and get the volume of the liquid in mL
Weigh the cylinder on the balance with the liquid still in the cylinder.
Subtract filled cylinder minus empty cylinder. That gives you the mass of the liquid in grams.
mass divided by volume is density.

Density = mass/volume (definition).
So it looks like all you need is a graduated flask and a balance. Weigh the flask empty, then full of the liquid up to the mark.
When stuck, go back to the definitions and let them do the heavy lifting for you.

you need a graduated cylinder, a cup to put the liquid in and a triple beam balance. u put the cup on the scale and measure, this is m1 then u put the liquid in the cup and measure, this is m2 subtract m1 from m2 this is the mass or m3 now put the liquid in the graduated cylinder and measure this is the volume or v1 now divide the mass m3 by the volume v1 and you have the density

again this is similar to the coin issue.
1. place unknown liquid in a known value displaced container.
2. place container in displacement measurement setup.
3. based on displacement calculate the relative density
