Okay -- because we know that the knowns were screwed up in lab this
week, some of the professors prepared a calibration curve for you.
Please graph the following data for you calibration curve and fit the
best line through the data. Your graph should also include the slope
of the best line.<br>
<br>
You should plot Absorbance on the Y axis and concentration of caffeine
on the X axis<br>
<br>
<table border="1" cellpadding="2" cellspacing="2" width="100%">
