In the attachment I am confused on how he/she got the answer and the right equation for data table 3 the far right

column under 1/average volume, 1/Vavg (1/mL). Iam working on a similar problem and of course I got different numbers for all the trials withing the book numbers. I cant seem to figure out how to do find and or use the proper equation to colve for 1/Vavg(1/mL) docx (1) example.docx

Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data
tables that should be addressed in a formal lab report. The intent is to facilitate students’
writing of lab reports by providing this information in an editable file which can be sent to an

A. Describe the relationship of pressure versus the volume of a confined gas.
Volume and pressure have an inverse relationship because as the volume of the container
increases, the pressure of the confined gas decreases.
B. Would you expect your experimental results would change if a different gas, such as CO 2,
were used instead of air? Explain your answer.
Yes I would expect that different gases would each have their own effect because the
density of the gases would vary.
C. Use a reliable source to determine the atmospheric pressure at your location (atmospheric
pressure at sea level is 101325 Pa and atmospheric pressure in Denver, Colorado is 84000
Pa). Use the equation below to calculate the percent difference between your experimental
value for atmospheric pressure and the theoretical value (actual atmospheric pressure).
Show all work. What are some possible sources of errors in your experiment? Percent Diffe rence = (Experimental Value - Theoretical Value)
(Theoretical Value) 15890-101325 = -0.843 x 100% = -84.3%
101325 D. As stated by Boyle’s Law, the products PV should equal a constant, k. Did your results of P t ×
Vavg come out approximately the same for k?
No they did not have a constant pressure.
