A 250 mL flask contains air at 1.005 atm and 24.7 °C.5 mL of ethanol is added, the flask is immediately sealed and then warmed to 95.5 °C, during which time a small amount of the ethanol vaporizes. The final pressure in the flask (stabilized at 95.5 °C) is 2.876 atm. a) What is the partial pressure of air, in the flask at 95.5 °C? b)A solution which contains 77.5 g of an unknown molecular compound in 342 g of water freezes at -5.18°C.What is the molar mass of the unknown?
