Question
Type II diabetics as a result of glucose intolerance and insulin insensitivity continued to be a problematic health issue, affecting millions of people worldwide. The concentration of glucose (C_6 H_12 O_6) in human blood before meal, was determined calorimetrically by a first year chemistry graduate to be 80 mg/100 ml. I. Calculate the determined molarity of glucose in blood before meals by the student. II. Assuming the actual glucose concentration in blood before meals is 7 mu M, calculate the relative error and the percentage relative error in the determined glucose concentration in blood by the students. III. Based on the result of your calculated errors, will you consider the results of glucose analysis accurate?Explanation / Answer
B. Glucose
I. concentration of glucose
= mass of glucose (g)/molar mass (g/mol) x volume solution (L)
= 0.080/180.156 x 0.1
= 0.0044 M
= 4400 uM
II. Original glucose level 7 uM
error = (4400-7) = 4393 uM
% error = 4393 x 100/4400
= 99.841 %
III. The concentration thus calculated in I. and II, differe greatly from one another, so the determination is not accurate.
