Question

If the absorbance value for your sample goes above 0.9, you must ___

A) Dilute the sample
B) Discard the sample
C) Repeat the experiment
D) Increase incubation time

Answer 1

If the absorbance value for your sample goes above 0.9, you must dilute the sample.

Step-by-step explanation:

If the absorbance value for your sample goes above 0.9, you must A) Dilute the sample.

Absorbance is a measure of how much light is absorbed by a sample. It is directly related to the concentration of the species being measured in the sample. When the absorbance value exceeds 0.9, it indicates that the concentration of the species is too high to produce accurate results. Diluting the sample reduces the concentration and brings the absorbance value within the desired range for accurate measurement.
