Fill in the following blanks. As the dye concentration increases, the absorbance of the light [linearly increases, linearly decreases, exponentially increases or exponentially decreases]. The dye concentration units are [molar (M), millimolar (mM) or grams per liter (g/L)] . Although most people wrongly conclude that absorbance has units nm, in fact, absorbance is unitless. This is because it results from a ratio of light through a colored sample relative to light intensity through a clear (blank) sample. The units for the slope of the graph would be [mM, 1/mM or nm] . Hint: the slope is the change in y values divided by the change in x values. The units for the y-intercept of the graph would be [nm, nM or unitless] . The value for the slope of the line that describes the absorbance data is [6.4597 or 0.0008] The value for the y-intercept of the line that describes the absorbance data is [6.4597 or 0.0008] .
