An hour after a meal,a patient's blood glucose level is 180 mg/dL.Express this glucose level as mass/mass percent concentration.(Assume the density of blood is 1.0g/mL. )

Question

Quizplus · Accepted Answer

To convert the glucose level to mass/mass percent concentration, we need to determine how much glucose is present in 100 mL of blood.

Assuming the density of blood is 1.0 g/mL, 100 mL of blood has a mass of 100 g.

If the glucose level is 180 mg/dL, then in 100 mL of blood, there are 180 mg of glucose.

To express this as mass/mass percent concentration, we need to divide the mass of glucose by the total mass of the solution (blood) and multiply by 100:

(180 mg / 100 g) x 100% = 0.18%

Therefore, the correct answer is C) 0.18%.
