The vapor pressure of benzene is 73.03 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in benzene is testosterone. Calculate the vapor pressure of the solution at 25 °C when 14.86 grams of testosterone, C19H28O2 (288.4 g/mol), are dissolved in 228.3 grams of benzene. benzene = C6H6 = 78.12 g/mol.
1. The vapor pressure of benzene is 73.03 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in benzene is testosterone. Calculate the vapor pressure of the solution at 25 °C when 14.86 grams of testosterone, C19H28O2 (288.4 g/mol), are dissolved in 228.3 grams of benzene. benzene = C6H6 = 78.12 g/mol.
2. The vapor pressure of water is 23.76 mm Hg at 25°C. How many grams of antifreeze (ethylene glycol), CH2OHCH2OH , a nonvolatile, nonelectrolyte (MW = 62.10 g/mol), must be added to 257.3 grams of water to reduce the vapor pressure to 23.32 mm Hg? water = = 18.02 g/mol.
3. 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 67.88 grams of the compound were dissolved in 297.6 grams of water, the vapor pressure of the solution was 23.23 mm Hg. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight of this compound? (Water = = 18.02 g/mol)
