Answer to Question #145567 in General Chemistry for Kelechi Agbi

Question

Beer's Law.
Standard Concentration Absorbance
50 mg/dL 0.150
100 mg/dL 0.300
200 mg/dL 0.600
300 mg/dL 0.900

50. Using the absorbance values and the concentration of each standard complete the appropriate standard curve.
51. If a patient sample was also analyzed at the same time that the standards were analyzed and had an absorbance value of 0.450, what would the glucose concentration of the sample be?

Answer 1

y = 0.003x

x = y/0.003

c = 0.450/0.003 = 150 mg/dL

the glucose concentration of the sample is 150 mg/dL

Answer: the glucose concentration of the sample is 150 mg/dL
