. Using your graphs from question 1, plot 0 to 200 m/s for each gas. Find the fraction (put your final answer in percent) of molecules with speeds in the range of 100 to 200 m/s. If you use the polynomial fit in excel find the order that best fits the graph between 100 to 200 m/s with scientific notation using 4 decimal places, you simply integrate it with limits of 100 to 200 m/s. To see this clearly plot each of these separately.
