Beer-Lambert Law Practice Test

A solution has concentration $1.0\times10^{-5}\ \text{M}$ and is measured in a 1.00 cm cuvette at a wavelength where $\varepsilon=3.0\times10^4\ \text{L mol}^{-1}\text{cm}^{-1}$. What absorbance is expected?

At 600 nm, a compound has $\varepsilon = 1.0\times 10^4,\text{M}^{-1}\text{cm}^{-1}$. A solution of this compound has concentration $c = 2.0\times 10^{-5},\text{M}$ and gives absorbance $A = 0.40$. What path length $\ell$ (in cm) was used?
