Question

What is the molarity of a solution prepared by dissolving 8.0 g of NaOH in enough water to make 2.0 L of solution? (Molar mass of NaOH = 40 g/mol)

• A. \( 0.10 \, \text{M} \)
• B. \( 0.15 \, \text{M} \)
• C. \( 0.20 \, \text{M} \)
• D. \( 0.25 \, \text{M} \)

Hint:

To find molarity, divide the number of moles of solute by the volume of the solution in liters.
