Thank you.
The chromium in q series of steel samples was determined by ICP emission spectroscopy. The spectrometer was calibrated with a series of standard concentrations of K₂Cr₂O7. The table below shows the calibration data. [K₂Cr₂O7] in µg/mL 0.0 2.0 4.0 Emission Readings 4.650 32.25 K₂Cr₂O7] in μg/mL 6.0 8.0 Emission Readings 87.50 116.0 61.35 a. Using linear regression, determine the equation of the calibration curve.
