What is the glucose concentration in ppm of a solution made by mixing 23.2 mg glucose with 2.000 L?

Question

Quizplus · Accepted Answer

The concentration in ppm (parts per million) is calculated as the mass of the solute (glucose) divided by the mass of the solution, then multiplied by 1,000,000. Since the solution volume is given in liters and assuming the density of the solution is approximately that of water (1 g/mL), 2.000 L of solution is equivalent to 2000 g. Therefore, the concentration of glucose is (23.2 mg / 2000 g) * 1,000,000 mg/g = 11.6 ppm.
