The density of a methanol$-$water solution that is $12\mathrm{.}000$ weight percent methanol is $0\mathrm{.}97942$ g$/$cm$\text{'}$ at $15\backslash$deg C and $1$ atm. For a solution that is $13\mathrm{.}000$ weight percent methanol, the density is $0\mathrm{.}97799$ g$/$cm$\text{'}$ at this T and P$.$ Since the change in solution composition is small, we can estimate Va byVA $=($aV$/$anA$)$T$.$P$.$Ma $=($AV$/$AnA$)$T$.$P$.$MCalculate V$($CH$,$OH$)$ for a methanol$-$water solution at $15\backslash$deg C and $1$ atm that is $122\%$ CHOH by weight. Then calculate VH$,$O$)$ for this solution.
