Mass, Volume, and Density
Experiment 3, on Measurements of Length, Volume and Density.
Volume Equations are given on page 37.
We will discuss the least counts and estimated fractions for the meter stick, Vernier caliper, Micrometer, Balance and Graduated Cylinder. Table 1, page 39.
You will be responsible to turn in:
Density Determination, Data Table 3, Page 41.
You must include:
The linear dimensions of the Rod, Sphere and Rectangular Block specifying the the type of element each object is made of and a minimum of two readings for each step as well as the average. All readings must be taken in centimeters.
Data Table 4, Page 42
The mass in grams for the same rod, Sphere and Rectangular Block, you used in table 3.
Their volume by using the mathematical equations found in page 37, all expressed in cm3
The mass in grams and the volume in cm3 of the irregular shape indicating the type of material of the irregular object.
The density in g/cm3 all of the above showing the mathematical calculations and percent error, using equation 1.2, page 7. Accepted Densities of Materials are found in Appendix A, Page 523, Table A1.
Units must be written next to each physical measurement in each step, not just the final answer.
Questions 3, 4 and 5, Pages 43 & 44. Your answers should always be brief and on target. Support your answers with formulas whenever possible, or a simple diagram, or even a short experiment if needed.
