2.
Molar absorbtivity is the measure of the
amount of light absorbed per unit length
amount of light absorbed per unit concentration
amount of light reflected and absorbed per unit concentration
None of the above
Answer: Option

No answer description is available. Let's discuss.

3.
Which of the following relationships between absorbance and %transmittance is incorrect?
A = log10 100 / %T
A = 2 - log10 %T
A = log10 1 / T
All are correct
Answer: Option
Explanation:
No answer description is available. Let's discuss.

4.
Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance?
Because %T cannot be measured as accurately as absorbance
Because %T is dependant on the power of the incident radiation
Because absorbance is proportional to the concentration of the analyte, whereas %T is not
none of the above

5.
In the past, IR spectra had to be aquired one wavelength at a time, which took a long time. Today quick spectra is due to the
the Fourier Transfer Algorithm allows us to scan all frequencies at once
light is faster today that it used to be
absence of broad spectrum of wavelenth
none of the above
