# How would you make 1 liter of a solution of 1.0 NaCl?

Take $58.4400 \cdot g$ of sodium chloride.........
Around $58 \cdot g$ is acceptable so long as it is accurately weighed; this is quantitatively transferred into a $1 L$ volumetric flask. Pour in distilled water and swirl until the solute is dissolved. Then carefully fill the flask up to the $1 \cdot L$ graduation with more distilled water.
$\text{Concentration}$ $=$ $\frac{58.4400 \cdot g}{58.44 \cdot g \cdot m o {l}^{-} 1} \times \frac{1}{1.000 \cdot L}$ $=$ ??mol*L^-1.
If I had a $250 \cdot m L$ volumetric flask, what mass of sodium chloride would I need in that instance?
