The Following Graph Is the Standard Curve for Absorbance of an Analyte

question 3

Multiple Choice

The following graph is the standard curve for absorbance of an analyte.
In the laboratory,you are presented with a solution with an unknown concentration of the analyte.You measure the absorbance of the solution and determine it to be 0.75.Can the analyte's concentration in the solution be determined using this standard curve?

• A) No, because glucose concentrations cannot exceed 0.016 mg/ml.
• B) No, because the concentration must be extrapolated.
• C) Yes, because the concentration can be interpolated.
• D) Yes, because the standard curve is linear.
