\n\n Calculated Concentration
\nThe concentration of the substance is:
\n \nMolarity (mol/L)
\n\n
\nHow This Works
\nThis calculator uses the Beer-Lambert Law, which states that the absorbance of a solution is directly proportional to the concentration of the absorbing species and the path length of the light through the solution.

} Explanation of Variables
\n| Variable | \nFull Name | \nTypical Units | \nDescription | \n
|---|---|---|---|
| A | \nAbsorbance | \nUnitless | \nThe amount of light absorbed by the solution. Measured by a spectrophotometer. | \n
| l | \nPath Length | \ncm | \nThe distance the light travels through the solution, usually the width of the cuvette. | \n
| ε | \nMolar Absorptivity | \nL/(mol·cm) | \nA constant that indicates how strongly a chemical species absorbs light at a given wavelength. | \n
| c | \nConcentration | \nmol/L | \nThe amount of solute dissolved in a solvent. | \n
