How do you determine the mole fraction of a monomer (f1) from the Molar Fraction Ratio (eg. I have the Molar Fraction Ratio of styrene: methylmethacrylate in a copolymer as 3.91 but do not know how to determine the monomer compositions of each of them so that I can then determine their reactivity ratios)?

I'm confused please help. If you are given an absorbance and wavelength graph, how do you find molar absorptivity? Is molar absorptivity from the graph itself or do you need to find this online to calculate concentration? And from the absorbance and wavelength graph, what is the use of knowing lambda max?

11. You produce a graph of absorbance vs. concentration which yields the equation y=1579.7x. If the concentration of salicylic acid increased by 1/3 would you expect the absorbance to also increase by 1/3? Explain your reasoning using Beer's law.

In the lab you obtained a velocity vs. time graph when a person was moving on a straight line with constant velocity away from the motion sensor. You highlighted a region of data containing 5 points with the following values of velocity: 0.38, 0.26, 0.29, 0.34, 0.34 m/s IMPORTANT NOTE: When you report your final result in the lab report, the number of the significant figures on the error should NOT be the same as the number of significant figures...
