See the following table of concentration, green intensity, blank. Based on these data, convert intensity data into absorbance. Make a plot of absorbance versus relative concentration. Find the equation for the best fit line on the plot. Concentration (M) Green intensity (I) Blank (lo) Absorbance (-log 1/10) 0.000 234 234 0.100 228 234 0.200 221 234 0.300 216 234 0.400 211 234 0.500 203 234 0.600 199 234 0.700 191 234 0.800 185 234 0.900 179 234 1.000 174 234 a) Show the best fit line as the form of y = ax + b for your answer. You do not need to show your plot. How much is the slope (m) in this best fit line as the form of y = mx + b in your answer? Type your answer... a) Let's assume that the best fit line is the form of y = 0.2291x-0.01310 for your result. b) If you have the absorbance of 0.0469 for the unknown solution, what could be the concentration (M) of this unknown solution? You should put your answer as a decimal form. Do not forget the proper number of significant figures. Type your answer...
