Ou have a solution of unknown concentration. You place this solution in your spectrometer and measure that it has an absorbance of 0.8 at 450 nm. The molar absorptivity of your product is 1500 L/moles·cm. Assuming that you are measuring the sample in a 1 cm path length cell what is the concentration of product in your solution? Report your answer in mM units.

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
