If we know the amount of light that is absorbed in a solution we can calculate the concentration of the substance dissolved in water using a spectrophotometer. For a certain substance the concentration (in moles/liter) is given by the formula where
is the intensity of the incident light and
is the intensity of light that emerges. What is the concentration of the substance if the intensity
is 45% of
?
A) 952 mol/L
B) -3667 mol/L
C) 2928 mol/L
D) 2192 mol/L
