The vapor pressure of diethyl ether $($ether$)$ is $463\mathrm{.}57$ mm Hg at $25\backslash$deg C$.$ A nonvolatile, nonelectrolyte that dissolves in diethyl ether is estrogen.

Calculate the vapor pressure of the solution at $25\backslash$deg C when $12\mathrm{.}00$ grams of estrogen, C$18$H$24$O$2(272\mathrm{.}4$ g$/$mol$),$ are dissolved in $254\mathrm{.}7$ grams of diethyl ether.

diethyl ether $=$ CH$3$CH$2$OCH$2$CH$3=74\mathrm{.}12$ g$/$mol$.$
