???????

Absorbance was measured for a diluted solution of crystal violet (CV), which was prepared by adding \( 0.500 \mathrm{~mL} \) of \( 1.128 \times 10^{-4} \mathrm{M} \) of \( \mathrm{CV} \) to \( 2.500 \mathrm{~mL} \) of water in a 1.00-cm wide quartz cuvette. The absorbance at the maximum wavelength for this solution was measured to be \( 1.19639 \mathrm{AU} \) (arbitrary units). Calculate the molar absorption coefficient for \( \mathrm{CV} \) at \( 589.2 \mathrm{~nm} \) to 3 significant figures without units: Answer: \( \quad \times 1 C \) (e.g., if the answer is 1110 , which is \( 1.11 \times 10^{3} \), type "1.11" into the 1 st blank, then "3" into the 2 nd blank)
