2. In one of the experiments this semester we will need to create a graph, find the best-fit slope for the data and determine how well the data fits the best-fit line. We will prepare solutions with known concentrations (mol/L) and measure the absorbance of each solution. We will use an instrument that measures how much light a compound absorbs at a specific wavelength (color). Copy the data in the table below in excel and create a scatter plot of absorbance versus concentration. Make sure the plot has the following features: y axis showing absorbance, x axis showing concentration in ppm plot created a separate sheet in the workbook • proper title labeled axes • sensible scales on the axes • no gridline • a colorless background to the plot solid green squares as data markers • a line of best fit (trendline) which passes through the origin set y intercept to zero the equation of the line and R? value to the four decimal places Concentration (parts per million, ppm) 20 Absorbance 0.736 15 0.556 10 0.702 0.206 2 0.084 3. Based off your R? value, make a statement about the quality of data. In other words, how well does your data fit a línear relationship?
