Answers | 100% Pass
Select the BEST answer.
The percentage oxyhaemoglobin in a haemoglobin solution can be calculated by:
using the ratio of absorbances of oxy- and deoxyhaemoglobin at wavelengths where the
biggest difference in absorbance readings are observed...
the log of the ratio of incident light to transmitted light
the ratio of concentration to transmitted light
the ratio of molar absorbance coefficient to lightpath length - Answer✔️✔️-the log of the
ratio of incident light to transmitted light
Beer's Law implies that:
the concentration of a solution is dependent on lightpath length
the distance light travels through a solution is independent of concentration
the molar absorbance coefficient is dependent on the concentration of the absorbing
solute
the absorption of light increases with increasing solute concentration - Answer✔️✔️-the
absorption of light increases with increasing solute concentration
When haemoglobin in oxygenated in the lungs it is most likely to: - Answer✔️✔️-
A 3 mL cuvette was filled with 0.5 mL of solution Y and 2.5 mL of water and its
absorbance at 340 nm was 0.394.
The molar absorbance coefficient of solution Y is 31,000 L/mol/cm. The pathlength is 1
cm.
