Question

The ultraviolet spectrum of benzonitrile shows a primary absorption band at 224 nm. If a
solution of benzonitrile in water, with a concentration of 1x 10-4 molar, is examined at a
wavelength of 224 nm, the absorbance is determined to be 1.30. The cell length is 1 cm. What
is the molar absorptivity of this absorption band?
a) 2.3 x 104
b) 3.3 x 104
c) 1.3 x 104
d) 4.3 x 10
