The molar extinction coefficient of benzene equals 100 M-1cm-1 at 260 nm. Assume this number is independent of solvent. (a) What concentration would give an absorbance of 1.0 in a 1 cm cell at 260 nm? (b) What concentration would allow only 1% of 260 nm light to be transmitted through a 1 cm cell? (c) If the density of liquid benzene is 0.8 g/cm3, what thickness of benzene would give an absorbance of 1.0 at 260 nm? A) Absorbance is A = c so c = A/.
