Definition: Absorbance of Unknown Metal is the logarithm of the ratio of incident to transmitted radiant power through a sample.
Purpose: This calculator helps determine the absorbance of an unknown metal sample by comparing it to a known metal standard.
The calculator uses the formula:
Where:
Explanation: The ratio of the unknown metal's strength to the known metal's strength is multiplied by the known metal's absorbance to estimate the unknown's absorbance.
Details: Accurate absorbance measurements are crucial in spectroscopy for determining concentrations, identifying substances, and analyzing material properties.
Tips: Enter the strength of both metals in mol/m³ and the absorbance of the known metal. All strength values must be > 0.
Q1: What units should I use for strength?
A: The calculator uses mol/m³ (moles per cubic meter) for consistency with SI units.
Q2: Can absorbance be negative?
A: No, absorbance values should always be zero or positive numbers.
Q3: What affects metal absorbance?
A: Absorbance depends on the material's composition, thickness, and the wavelength of light used.
Q4: How accurate is this calculation?
A: Accuracy depends on precise measurement of both metal strengths and the known metal's absorbance.
Q5: What if my unknown metal has different properties?
A: This calculation assumes similar absorption characteristics between the known and unknown metals.
