Question 1
A liquid sample absorbs light at a wavelength of 550 nm and has an absorbance of 0.500 with a path length of 1 cm. If the molar absorptivity is 50 L mol⁻¹ cm⁻¹, determine the concentration.
💡 Hint: Use the Beer’s Law equation.
Question 2
Given two samples, one with an absorbance of 0.700 and another with 0.350, how do you expect their concentrations to compare?
💡 Hint: Refer back to Beer’s Law for proportionality.
