Default How do I read unknown values from an existing chart?

I am using an XY scatter chart to plot Absorbance readings vs. Concentration.
What I would like to do is plug in and unknown absorbance and it return a
concentration read from the chart. Any suggestions?

Don't use the chart, use the spreadsheet.
