This depends upon the phase of the material whose density you wish to find. Fir an irregularly shaped solid, you would have to find the volume using a graduated cylinder (to measure how much liquid it displaces) and then weigh it on a scale (probably a triple beam balance). A regularly shaped solid would not require a graduated cylinder, you could just get its measurements with a ruler. A liquid could be measured using a graduated cylinder and a scale. A gas could have its density relative to that of the air measured by observing its buoyancy vs. weight measured in a balloon. That is a bit more complicated.
The Tools You need to find Density of an object is you divide the mass of the object with the volume of the object
Use a mass balance to find the mass then find the volume by V=mass/density.
Grams. Obviously.
Its volume.
Use the triple beam balance to find
Use the compounds density.
Hydrometer is used in batteries to measure density. A float tells you the density using displacement.
Density is a physical property of matter: it is not a tool.
Measure the container itself, or measure the mass of the liquid and the container and find the density of that certain liquid has and isolate for the volume.
What is a tool that scientists use to find patterns in their data
What tool you should use depends on what you want to achieve.
Mass = Density -------- volume
the tool used to find the width of a pencil is a ruler. But use the centimeter side of it for the width only!!
Hydrometer
divison
Use a mass balance to find the mass then find the volume by V=mass/density.
Find the mass of a known volume of the liquid and use the formula mass/volume to find the density.
