Concept explainers
(a)
Interpretation:
The absorbance 0.0865 is to be converted into percent transmittance.
Concept introduction:
The percent of light passing through the sample can be reported in a transmittance. In order to calculate the percent transmittance, the transmittance is multiplied by 100.
(b)
Interpretation:
The absorbance 0.3995 is to be converted into percent transmittance.
Concept introduction:
The percent of light passing through the sample can be reported in a transmittance. In order to calculate the percent transmittance, the transmittance is multiplied by 100.
(c)
Interpretation:
The absorbance 0.5725 needs to be converted into percent transmittance.
Concept introduction:
The percent of light passing through the sample can be reported in a transmittance. In order to calculate the percent transmittance, the transmittance is multiplied by 100.
(d)
Interpretation:
Need to convert absorbance 0.028 into percent transmittance.
Concept introduction:
The percent of light passing through the sample can be reported in a transmittance. In order to calculate the percent transmittance, the transmittance is multiplied by 100.
