Step 1
Step 1: Recall Beer's Law, which is given by the equation: \[ A = \varepsilon \cdot c \cdot l \] where \( A \) is the absorbance, \( \varepsilon \) is the molar absorptivity, \( c \) is the concentration, and \( l \) is the path length. Show more…

The molar absorptivity of a compound at 500 nm wavelength is 252 M⁻¹cm⁻¹. Suppose one prepares a solution by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution. What would be the absorbance in a 9.00 mm pathlength cell?
