3. Using the given data, calculate the missing values ​​in the table:
Optical density (A) Molar absorption coefficient, ε Layer thickness, l cm Concentration
SOLUTION FOR ALL FIVE OPTIONS:
0.345 x 2.00 4.25*10-4 M
x 3.7*104 1.75 1.20 μg/ml (mol mass 325)
0.176 5.2*104 X 2.26*10-5 M
0.982 2.75*104 0.98 X M
0.634 2.98*104 2.00 μg/ml (mol mass 184)
