I?m not understanding any of this could someone help please


Plot the following data as absorbance versus[XX] as a calibration curve:

 

Absorbance

 

0.0453

 

0.097

 

0.14

 

0.35

 

0.51

 

Standard Concentration of XX

 

3.0 *10^-4 mol/L

 

6.2*10^-4 mol/L

 

9.0*10^-4 mol/L

 

2.2*10^-3 mol/L

 

3.2*10^-3 mol/L

 

A "test" solution showed a percent transmittance(%T) reading 55%T.Interpret the calibration

 

curve to determine the molar concentration of XX in the test solution.Please include a graph

 

model so I can plot the coordinates properly.

 

The plot that indicates the relation between the absorbance Vs concentration

 

x-Concnetration

 

y-absorbance

 


 

From the plot ?

 

y = 160.3x

 

Since ?

 


 

A = ? lc ( wherel =1 dm 3 )

 


 

When compared with the above equation, we get - ? = 160.3

 

Since ?

 

%transmittance = 55%

 

T = 0.55

 

Therefore ?

 

A = -log T = -log(0.55) = (160.3)[XX]

 

[XX] = 1.61*10^-3 M
