To convert transmittance data to absorbance, we can use Beer-Lambert law, which states that the absorbance (A) is related to the transmittance (T) by the equation:
where T is the transmittance expressed as a decimal.Let's calculate the absorbance for each given transmittance value:(a)
(b) 0.579
(c)
(d)
(e) 0.093
(f)
Now, let's calculate the percent transmittance of a solution that has twice the absorbance of the solutions in Problem 24-14.Assuming the absorbance values from Problem 24-14 are as follows:- Solution 1: 0.5- Solution 2: 1.0- Solution 3: 1.5Twice the absorbance of the highest value (1.5) is:
Using the Beer-Lambert law in reverse to find the transmittance:
Converting this to percent transmittance:
Therefore, the percent transmittance of the solution with twice the absorbance of the solutions in Problem 24-14 is 0.1%.
