Determining Unknown's Concentration
  • Unknown from: Zach, Eleni, Moira
  • Concentration determined from our calibration curve: 1.164x10-5
  • Concentration determined from class calibration curve: 1.323x10-5
  • Actual concentration:

Matt Hartings I'd like to see the group calibration curve. I'd also like some quantification of error in your concentration calibrations.
