3.7 Solutions and Mixtures
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?
