Since there is a direct relationship between absorbance and concentration of Beer's law, the units for the slope (product of molar absorptivity and path length) are:
Question 4 options: (I chose number 1 because the molar absorvity of a solute is in units of M^-1cm^-1. Is this correct?)

Homework Answers
A = e*l*C
we need to find the unit of e*l
e*l = A/C
A is absorbance which is unit less
unit of C is M
So, unit of e*l = 1/M = M-1

A student measures the absorbance of a solution at some point during the reaction and records a value of 0.335 . (Note that absorbance has no units.) Use Beer's Law and the constants given on page 5 to calculate the concentration of crystal violet in this solution. *The relationship between the solution absorbance and the CV+ concentration can be written as shown in Equation 7 below (Beer’s Law). At = ε∙b∙ct [7] In Equation 7, At is the reaction solution...

Question 4 (10 points) Beer's Law states A = ebc. A is the absorbance, the product of the three other variables. Which definition of the three variables is not correct? e is the molar extinction coefficient, or molar absorbtivity, a constant that is peculiar to the absorbing species, in L/mol-cm. O cis the concentration in moles/Liter. This is the variable we analyze for. O b is the thickness or viscosity of the solution. All of these definitions are correct.
