Question

What is the molarity of a solution prepared by dissolving 5.85 g of NaCl in water to make 250 mL of solution? (Molar mass of NaCl = \( 58.5 \, \text{g/mol} \)).

• A. \( 0.1 \, \text{M} \)
• B. \( 0.2 \, \text{M} \)
• C. \( 0.4 \, \text{M} \)
• D. \( 1.0 \, \text{M} \)

Hint:

When calculating molarity, convert the volume to liters and ensure the mass is divided by the correct molar mass to find moles. Double-check unit conversions to avoid errors.
