Tīmeklis2016. gada 4. febr. · The equation for Beer’s law is a straight line with the general form of y = mx +b. Beer’s Law: A = ( l)c with the general form y = (m)x where the slope, m, is equal to l. In this case, use the absorbance found for your unknown, along with the slope of your best fit line, to determine c, the concentration of the unknown solution. TīmeklisBeer’s contribution dates back to late 1852 [5]. Brieﬂy, the law correlates the radiant power in a beam of electromagnetic radiation (e.g. ordinary light) to both the length of the path of the beam in an absorbing medium and to its concentration [6].
