Theoretical y intercept based on beer's law
Webb7 dec. 2015 · The Mathematics of Beer’s Law – Concentration tabBeer’s law is a linear relationship between absorbance (A) and three independent variables:the molar absorptivity (a), the pathlength (b), and the concentration (c). The law takesthe form of y = mx + b, where m is the slope and b is the y-intercept.
