How much of 0.5 M glucose (molecular mass 180) is needed to provide 100 mg of glucose?

Question

Quizplus · Accepted Answer

To find the volume of 0.5 M glucose solution needed to provide 100 mg of glucose, first convert 100 mg to grams (0.1 g). Then, calculate the moles of glucose: 0.1 g / 180 g/mol = 0.000556 mol. Since the solution is 0.5 M, use the formula: moles = molarity × volume (in L). Rearranging gives volume = moles / molarity = 0.000556 mol / 0.5 mol/L = 0.00111 L, which is 1.11 mL.
