I am unsure exactly how to set up this calculation. From a graph that we got from getting different absorbances we took those points we got and got a equation for the best fit line. The equation was y = 760.8x + .02014 and the unknown absorbance equalled .254. We than wanted to determine the permanganate ion concentreation in the solution using the equation for the line. how exactly would you go about doing that?
