5. Determine the percent transmittance of B-carotene, C40H56 that has an absorbance of 0.5when analyse using a UV-Visible spectrophotometer.A. 6.83%B. 31.6%C. 0.32 %D. 68.3%6. The equation of Beer Lambert's Law is A = abc. If the 'b' is distance, 'a' is absorptivity,and 'A' is absorbance, what does the 'c' represent?A. IntensityB. Analyte concentrationC. Analyte transmittanceD. Frequency7. All the following is an example of photon detectors EXCEPT:A. Vacuum phototubeB. Silicon photodiodesC. BolometersD. Photomultiplier tubes8. C=O bond stretch occurs at 1750 cm1 and C-O stretch occurs at 1100 cm1 because:A. The C-O has a single bond which is a stronger bond, so it vibrates at a higherfrequency than the C=O.B. The C-O has a single bond which is a stronger bond, so it vibrates at a lowerfrequency than the C=O.C. The C=O has a double bond which is a stronger bond, so it vibrates at a lowerfrequency than the C-O.D. The C=O has a double bond which is a stronger bond, so it vibrates at a higherfrequency than the C-O.9. Following are the advantages of double-beam instrumentation EXCEPT:A. Compensate for all but most short-term fluctuations in the radiant output of the sourceas well as for drift in the transducer and amplifierB. Suited for quantitative absorption measurements at a single wavelengthC. Compensate for wide variations in source intensity with AD. Continuous recording of transmittance or absorbance spectra
