Calculate Mn & Mw, and the polydispersity index (PI) for the molecular weight data provided below and graph. Repeat your calculations if the molecular weight data were changed by increasing the frequency (# of chains) of the following molecular weights by 500: 600, 700, 800, 900, 1000, and 1100 and graph.
Explain what happens to the PI and what this means in terms of molecular weight distribution. Input data and graph in Excel or similar graphing program and dropbox your Excel file (both graphs along with the Mw, Mn, and PI for each each data set). Don't forget to put your name in the Excel filename.
