Which number best represents the slope of the graphed line? A. -2

B. -1/2

C. 1/2

D. 2

5: 20

step-by-step explanation:

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website

the formula for converting absorbance to transmittance goes as:

a = log (1/t)  a = 2 - log(%t)  10^a = 1/t  t = 10^-a  %t = 100(10^-a)

so at the given value of a,   a = 1.5

%t = 100(10^-1.5)

%t = 3.16%
