3. Sample Calculations:
Avg. Diameter Cylinder = (D1 + D2 + D3 + D4 + D5 + D6)/6
Avg. Diameter Cylinder = plug values in the formula
Avg. Diameter cylinder =
cm
Corrected Avg. Diameter = Avg. Diameter – Zero reading
CAD = plug values in the formula
CAD =
cm
Volume (cylinder) = (π*d2average*haverage)/4
Volume (cylinder) = plug numbers
Volume (cylinder) = ___________ cm3
Density = ρexp = Mass/Volume
ρexp = plug values in the formula
ρexp = ____________ g/cm3
4. Graph
Here you will include your excel chart. The chart must be by itself in a single page
and print landscape. Print the chart directly from excel and include the printout at this
point. Read the Lab report format handout for the chart’s proper format.
I have also included a sample of the chart for you. Please notice that the data used in
the sample chart is not valid for this experiment.
Only include the chart here, do not include the spreadsheet with the data.
