Question

What is the volume of solution needed to prepare a 3 Molarity (M) solution containing 80 g of NaOH?

• A. 1.50 L / 1500 mL
• B. 1.33 L / 1330 mL
• C. 0.67 L / 667 mL
• D. 0.50 L / 500 mL

Hint:

To calculate the volume of solution needed for a given molarity, always use the molarity formula $M = \frac{\text{moles}}{V}$ and convert mass to moles using the molar mass.
