If a student needs to make a 0.10 M solution of NaHCO₃, how many milliliters of solution can be made using a 0.35-g sample of NaHCO₃?

Question

Quizplus · Accepted Answer

The molar mass of NaHCO₃ is approximately 84 g/mol. A 0.35 g sample corresponds to 0.35/84 moles. To make a 0.10 M solution, the volume in liters is calculated by dividing the moles by the molarity, which gives approximately 0.0042 L or 42 mL.
