A 50.0 mg sample was dissolved in acid and then diluted to a total volume of 50.00 mL. If 1.000 mL ofthis solution was then diluted to 50.00 mL with water. If this diluted solution had a transmittance of 0.275 at520 nm, what is the concentration of KMnO4 in ppm in this diluted solution, assuming no interference fromother species at this wavelength?

The transmittance of a solution is found to be 85.0% when measured in a cell whose path length is 1.00 cm. What is the percent transmittance if the pathlength is increased to 10.00 cm? 19.7%

During your experiment, you measure the absorbance of a sample to be 1.362. You have to convert thisabsorbance to methylene blue concentration (in ppm) using the absorbance measurements of two standardsolutions of known concentration:5 ppm: Absorbance 0.55510 ppm: Absorbance 1.211What is, in ppm, the concentration of your sample? Report using 3 decimal figures. Your answer must becorrect to 0.02 ppm
