A graph of this data revealed the line equation Is y=.0166x-.1223 with an R^2 square value of .99234

a. a. Evan measures an unknown solution with an absorbance of .448. What is the concentration of the solution?

b. b. Evan takes 1.0 ml of a solution and dilutes it to 50.0ml. The absorbance is .192. What is the concentration of the original solution?

\\plplease show work!!!!

a) given y= 0.448 , therfore from y=.0166x-.1223, x= 34.355 nM

b) again, y=0.192 , therfore x=18.93M, therfore concentration of original solution = 50*18.93 = 946.5 nM
