Quizplus · Accepted Answer

The number of moles of sulfuric acid is calculated using the formula: moles = concentration (M) × volume (L). Here, the volume needs to be converted from mL to L: 0.250 mL = 0.000250 L. Thus, moles = 0.500 M × 0.000250 L = 0.000125 moles, which is option A when expressed in standard form.
