(3)  MULTIPLE CHOICE:  Chapter 1–Part 2:  Measurement (56 points) 28 questions x 2 points each

For the graduated cylinders pictured below: (a) Record the measurement to the correct number of significant figures and units.(b) Determine & record the uncertainty of the measurement.(c) Determine and state which instrument would give the most REPRODUCIBLE result. Graduated Cylinder #1      Graduated Cylinder #2    

(4)  MULTIPLE CHOICE:  Chapter 1–Part 2:  Measurement (27 points) 7 PROBLEMS:  The following questions require to perform a Density or Dimensional Analysis calculation to solve the problem. Although the problems are in a Multiple Choice format, you still must solve the problem and report answer to proper number of significant figures. Please make sure you select the answer option with the correct number of significant figures based on the measurement and conversion factors provided. Partial credit will be given, if you select the answer option that is correct but is not the correct number of significant figures.

Two samples of matter have been collected and the elemental composition was determined. Both samples were determined to contain carbon and oxygen. Evaluate the data collected for the two samples of matter shown below: Sample A                           Sample B 24.0 g C: 32.0 g O                             3.0 g C: 4.0 g O   Are these two samples the same compound or are they different compounds? Explain your answer and support your answer with Data and a Law.  Write in complete sentences for full credit.
