In a spectrophotometric analysis, a solution absorbs 0.602 units at 450 nm. If the path length is 1.0 cm and the molar absorptivity is 1.5 × 10³ L/mol•cm, what is the concentration of the solution?
Correct answer: A. 4.01 × 10⁻⁴ M
- A. 4.01 × 10⁻⁴ M
- B. 2.01 × 10⁻³ M
- C. 4.01 × 10⁻³ M
- D. 9.03 × 10⁻⁴ M
Explanation
Beer-Lambert Law: A = ε × c × l. Concentration c = A/(ε × l) = 0.602/(1.5 × 10³ × 1.0) = 4.01 × 10⁻⁴ M.
