The common laboratory solvent diethyl ether (ether) is often used to purify substances dissolved in it. The vapor pressure of diethyl ether , $${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{OCH}}_2{\mathrm{CH}}_3$$, is $$463.57\mathrm{mm}\mathrm{Hg}$$ at $$25^{?}\mathrm{C}$$. In a Laboratory experiment, students synthesized a new compound and found that when $$65.58$$ grams of the compound were dissolved in $$209.6$$ grams of diethyl ether, the vapor pressure of the solution was $$451.84\mathrm{mm}\mathrm{Hg}$$. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight of this compound? (Diethyl ether $$={\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{OCH}}_2{\mathrm{CH}}_3=74.12\mathrm{g}/\mathrm{mol}$$ ) Molecular weight = $$\mathrm{g}/\mathrm{mol}$$
