A photomultiplier tube with a linear response to radiation registered 83.2 μA with a blank solution in the light path. Replacing the blank with the solution of interest lead to a response of 45.1 μA.
a) Calculate the percent transmission of this solution assuming
zero dark current.
b) Calculate the percent transmission of this solution assuming 5.1
μA of dark current.
c) The absorbance of this solution assuming 5.1 μA of dark
current.
d) The current from the photomultiplier tube with a solution that
has one third of the concentration of the original solution.
e) The current from the photomultiplier tube if the blank shows 5.1
μA of dark current with the above solution?
