All parts of one question. please help The common laboratory solvent water is often used to purify substances dissolved in it. The vapor pressure of water is 23.76 mm Hg at 25 °C. In a laboratory experiment, students synthesized a new compound and found that when 79.28 grams of the compound were dissolved in 211.4 grams of water, the vapor pressure of the solution was 23.30 mm Hg. The compound was also found to be nonvolatile and a non-electrolyte. What...
