The common laboratory solvent ethanol is often used to purify substances dissolved in it. The vapor pressure of ethanol, CH2CH,OH, is 54.68 mm Hg at 25 °C In a laboratory experiment, students synthesized a new compound and found that when 35.52 grams of the compound were dissolved in 246.7 grams of ethanol, the vapor pressure of the solution was 53.38 mm Hg. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight of this...
