# Density of liquids and solids lab report

Add approximately 10 pellets, and record the new volume after the addition. To measure the density of a sample of a substance, it is necessary to measure its mass and volume.

Note that, since the measurements were made in a graduated cylinder, which is less precise than a volumetric flask, the density has lower degree of precision.

Most solid substances are irregularly shaped, which complicates volume determination. For both solids and liquids, a balance can be used to measure mass; however, methods for determining volume are different for solids and liquids.

This will allow the students to observe the effect that time has on the layers. Add another mL of distilled water to the graduated cylinder.

Part C: Graphical Analysis of Mass and Volume Data of an Unknown Solid Check out a ruler from the stockroom and obtain a tube containing cylindrical pieces of an unknown solid material from your instructor. For best results, repeat steps 2.

This is because if there is no mass, the volume must also be zero. Again, start with the smallest object first and progress in order of increasing object size.

### Density of liquids and solids pre lab answers

Density is useful for identifying or validating pure materials, such as elements or other species of known purity. Most solid substances are irregularly shaped, which complicates volume determination. Density, defined as a substance's mass per unit volume, is an important physical property for characterizing a material or chemical system. Add mL of distilled water to the graduated cylinder. This demonstrates that a solid's ability to float or sink depends on its density relative to the liquid it is in. Your browser does not support the video tag. Principles By definition, all matter has mass and occupies volume. The liquids and solids should be added to the mL beaker in the following order: Pour the corn syrup or concentrated salt solution into the beaker. Note that the measured densities are constant within experimental error for both substances. Note that, since the measurements were made in a graduated cylinder, which is less precise than a volumetric flask, the density has lower degree of precision. Measure the volume of the water very carefully.

Repeat step 3 to obtain a third set of mass and volume measurements. All matter has mass, and that mass occupies a specific volume.
