Most of the concentration are calculated using factor, this factor is?
a. Std absorbance / std value
b. Std value / std absorbance
c. Std value x std absorbance
(b) For methods obeying Beer's law, slope of the calibration curve (Cs/As) provides a constant to calculate the unknown concentration. Also depending on the formula:
At x Cs = As x Ct, thus, Ct=(Cs/As)x As
