Questions & Step-by-Step Solutions
If a solution has a concentration of 0.1 M and a path length of 1 cm, what is the absorbance if ε = 200 L/(mol·cm)?
Step 1: Identify the values given in the problem. We have a concentration (c) of 0.1 M, a path length (l) of 1 cm, and the molar absorptivity (ε) of 200 L/(mol·cm).
Step 2: Write down the Beer-Lambert Law formula: A = εcl, where A is the absorbance.
Step 3: Substitute the values into the formula: A = 200 L/(mol·cm) * 0.1 mol/L * 1 cm.
