Set IHMR
A		Relative Concentration
Methyl Red		Absorbance (a.u.)
at 425 nm
A01.000.094
A10.750.058
A20.500.041
A30.250.030
Set IIHMR
A		Relative Concentration
Methyl Red		Absorbance (a.u.)
at 520 nm
A01.000.895
A10.750.806
A20.500.597
A30.250.224
Set IMR-
B		Relative Concentration
Methyl Red		Absorbance (a.u.)
at 425 nm
B01.000.480
B10.750.302
B20.500.243
B30.250.052
Set IIMR-
B		Relative Concentration
Methyl Red		Absorbance (a.u.)
at 520 nm
B01.000.048
B10.750.033
B20.500.023
B30.250.017

Based on the data above, calculate the slope of the line of theabsorbance vs relative concentration for each for the four datasets (Part III in your lab manual).

Let:

αHMR
IA equal the slope for solutions A0-A3 at 425mm

αMR-
IB equal the slope for solutions B0-B3 at 425mm

αHMR
IIA equal the slope for solutions A0-A3 at520 mm

αMR-
IIB equal the slope for solutions B0-B3 at520 mm

These α's are the respective Beer's Law constants for HMR andMR- at the 2 wavelengths. Enter below the α's that youdetermined from your Excel graphs
