The vapor pressure of diethyl ether (ether) is 463.57 mmHg at 25∘C. A nonvolatile, nonelectrolyte that dissolves in diethyl ether is chlorophyll. Calculate the vapor pressure of the solution at 25∘C when 9.543 grams of chlorophylI, C55​H72​MgN4​O5​(893.5 g/mol), are dissolved in 262.6grams of diethyl ether. diethyl ether =CH3​CH2​OCH2​CH3​=74.12 g/mol. VP( solution )=mmHg
The vapor pressure of benzene is 73.03 mmHg at 25∘C. How many grams of cholesterol, C27​H46​O, a nonvolatile, nonelectrolyte (MW= 386.6 g/mol ), must be added to 255.7grams of benzene to reduce the vapor pressure to 70.98 mmHg ? benzene =C6​H6​=78.12 g/mol. Mass = g
