The solubility of $)=(58\frac{g}{m}ol$ in water at $25C$ is $360\frac{g}{L},$ and in methanol $14\mathrm{.}9\frac{g}{L}.$

What is the molarity of the aqueous and alcoholic saline solutions?

What part of $1L$ of seawater needs to be evaporated before we can observe salt crystals $($assume NaCl$3\mathrm{.}5\%\frac{w}{v})?$
