A solution of 75.0 g of benzene (C6H6) and 75.0 g of toluene (C7H8) has a total vapor pressure of 80.9 mmHg at 303 K. Another solution of 100.0 g benzene and 50.0 g toluene has a total vapor pressure of 93.9 mmHg at this temperature.
Find the vapor pressure of pure Benzene at 303 K
From the same container under the same conditions--same temperature and initial pressure, it takes 40 s for 1.00 L of O2 gas to effuse. Calculate the molar mass (in grams/mol) of the unknown gas.
