Match each solution with its corresponding mass of solute.
-25.0 mL of 0.10 M NaCl

Question

Quizplus · Accepted Answer

To find the mass of solute in a solution, you can use the formula mass = molarity (M) × volume (L) × molar mass (g/mol). For NaCl, the molar mass is approximately 58.44 g/mol. Convert 25.0 mL to liters (0.025 L), then multiply by the molarity (0.10 M) and the molar mass of NaCl. This gives 0.025 L × 0.10 mol/L × 58.44 g/mol = 1.461 g. However, since none of the options exactly match this calculation and option B is the closest reasonable approximation given the options, it seems there was a mistake in my calculation. Correctly, the calculation should be: $0.025 \, \text{L} \times 0.10 \, \text{mol/L} \times 58.44 \, \text{g/mol} = 0.1461 \, \text{g}$, which rounds to approximately 0.15 g, matching option B.
