As part of your lab writeup for Lab 5, you will need to hand in three properly labeled graphs:
Graph 1: Absorbance versus Wavelength – Indicate λmax and its value on the graph [Graph the fine scan only] Graph 2: %Transmittance versus Wavelength – Indicate λmax and its value on the graph [Graph the . . . → Read More: Lab 5 – Tips on how to draw the 3 graphs
Based on the following set of data,
the graph generated would be
For this graph that you are generating for next week, keep all the digits.
You need to convert all the temperature readings to Kelvin, so add 273.15. (Keep all digits) You need to take the inverse of temperature readings that have been converted to Kevin. (Keep all digits) You need to take the natural . . . → Read More: TP2 graph: Tips on graphing
From page 1, we learned that if we believe the temperatures were poorly measured, it would lead to the determination of ΔHvap of water to 2 significant figures.
But the graph of the data shows a very good fit of the data to a straight line ( R2= 0.998), so maybe the temperature measurements . . . → Read More: Where is the error in the “ln P Vs. 1/T” graph? Consider statistical errors (2 of 2)
Take a look at the two-column data.
