A certain wavelength. What is the molar absorptivity of compound A at that wavelength?
Molar absorptivity (ε) is defined as the ability of a substance to absorb light at a specific wavelength per unit concentration. It is calculated using the Beer-Lambert law:
A = ε l c
where A is the absorbance, ε is the molar absorptivity, l is the path length (in this case, 1 cm), and c is the concentration in moles per liter (M).
Transmittance (T) is the fraction of light that passes through a sample, and is related to absorbance by:
T = 10^(-A)
At 50% transmittance, T = 0.5, and therefore A = -log(T) = -log(0.5) = 0.301.
Substituting the values into the Beer-Lambert law:
0.301 = ε x 1 x 0.1
Solving for ε:
ε = 0.301 / (1 x 0.1) = 3.01 L mol^(-1) cm^(-1)
Therefore, the molar absorptivity of compound A at that wavelength is 3.01 L mol^(-1) cm^(-1).
