SUMMARY
To convert transmittance (%T) to absorbance (A), use the formula A = -log10(%T/100). In the case of a solution with a transmittance value of 58.8%, the absorbance is calculated as A = -log10(58.8/100), resulting in an absorbance of 0.232, reported to three significant figures. This conversion is essential in spectrophotometry for analyzing the concentration of solutions.
