Should I Include the Blank in My Calibration Curve Graph?

Homework Statement

Hi. I have a table where there is an absorbance for a 0.00 concentration (blank). I now that I have to substract that value to to each of the other absorbances that I have, but my question is... Do I have to graph (concentration 0.00, absorbance 0.00) in the calibration curve?

No need for that. Simply draw a curve If you read the result from the curve it is automatically adjusted for the blank.
