Introduction: The density of a material is defined as its mass per unit volume. The formula to find density is density=mass/volume. The most common units for density are g/mL or g/cm^3(remember 1 mL is equivalent to 1 cm^3). In this lab, you will determine the density of several volumes of an unknown liquid solution called “solution X.” You must then use your data determine whether the density of the solution is an intensive or extensive. An intensive property is a physical property of matter that does not depend on the size or the amount of material in the sample. Color, for example is an intensive property; no matter how much strawberry Jell-O you have it’s always red. By contrast, an extensive property does depend on the size or the amount of material in the sample. Weight is an extensive property; the larger a sample of Jell-O is, the more it weighs.
Hypothesis: If the mass and volume of solution X increases, then the density will remain the same, because density is an intensive property.
100mL graduated cylinder
250 mL beaker
1. Weigh a clean, dry, 100 mL graduated cylinder. Record the mass in the data section below.
2. Fill a 250 mL beaker with about 100 mL of solution X.
3. Add approximately 10 mL of the solution to the graduated cylinder. Record the volume of the liquid in the cylinder.
4. Weigh the graduated cylinder and liquid. Record…
