A solution has a %T value of 75.4% at 600 nm. What is the absorbance of this solution at this wavelength?
A = log (1/T) or log (100/%T)
To determine the absorbance of the solution, we need to use the formula:
Absorbance (A) = -log(%T/100)
In this case, the %T value is 75.4%. So, we substitute this value into the formula:
A = -log(75.4/100)
Next, calculate the ratio inside the logarithm:
75.4/100 = 0.754
Now, take the logarithm of this ratio:
log(0.754) = -0.1213
Finally, find the negative value:
A = -(-0.1213) = 0.1213
Thus, the absorbance of the solution at a wavelength of 600 nm is 0.1213.
