After fasting overnight,a patient's normal blood glucose level is 70-90 mg/dL.Express this range as mass/mass percent concentration.(Assume the density of blood is 1.0 g/mL. )

Question

Quizplus · Accepted Answer

To express mass/mass percent concentration, we need to divide the mass of solute (glucose) by the mass of solution (blood) and then multiply by 100. Assuming the density of blood is 1.0 g/mL, the mass of solution (blood) is equal to the volume of blood, which is 1 mL. Therefore, the mass/mass percent concentration of glucose in blood is:

(70-90 mg/dL) / (1000 mg/g) / (1 g/mL) x 100 = 0.07-0.09%
