Using Beer's Law determine the concentration of a dye dissolved in water that has an absorptivity of 1 x 102 cm-1M-1 and produce
Mnenie [13.5K]

Answer:

1 × 10⁻² M

Explanation:

Step 1: Given data

Absorptivity of a dye (ε): 1 × 10² cm⁻¹M⁻¹

Absorbance (A): 1.0

Length of the cuvette (l): 1 cm

Concentration of a dye (C): ?

Step 2: Calculate the concentration of the dye

We will use Beer's Law.

A = ε × l × C

C = A / ε × l

C = 1.0 / 1 × 10² cm⁻¹M⁻¹ × 1 cm

C = 1 × 10⁻² M

The concentration of the dye is 1 × 10⁻² M.
