# A student measures \(50.0 \text{ mL}\) of a \(0.500 \text{ M } \text{NaCl(aq)}\) standard stock solution and transfers it to a \(250.0 \text{ mL}\) volumetric flask, adding distilled water to fill the flask to the mark. The student then pipets a \(50.0 \text{ mL}\) aliquot of this diluted solution into a clean beaker. What is the mass of \(\text{NaCl}\) (molar mass \(58.44 \text{ g/mol}\)) present in the beaker?

A student measures \(50.0 \text{ mL}\) of a \(0.500 \text{ M } \text{NaCl(aq)}\) standard stock solution and transfers it to a \(250.0 \text{ mL}\) volumetric flask, adding distilled water to fill the flask to the mark.

- **A.** \(0.292 \text{ g}\)
- **B.** \(0.584 \text{ g}\)
- **C.** \(1.46 \text{ g}\)
- **D.** \(7.31 \text{ g}\)
