What is the concentration of chromate?? 1. The problem statement, all variables and given/known data A solution of K2CrO4 has an absorbance value 0.555 in a cell of 1.00cm path-length at a wavelength of 370nm. The value of the molar absorbtivity is 5.25x103M-1cm-1 for K2CrO4 at the wavelength. What is the concentration of this chromate solution? Report with Three significant figures. 2. Relevant equations Molar mass of K2CrO4 - 194.2 absorbance value is .555 at a wavelength of 370nm molar absorbtivity - 5.25*10^3M^-1cm^-1 3. The attempt at a solution I would attempted this but I have no clue how to get it to work really hard lol, I dont understand how I can even go about starting this please please help!!!
