The vapor pressure of liquid propanol, C₂H,OH, is 100 mm Hg at 326 K. A sample of C₂H,OH is placed in a closed, evacuated 512 mL container at a temperature of 326 K. It is found that all of the C,H,OH is in the vapor phase and that the pressure is 54.0 mm Hg. If the volume of the container is reduced to 390 mL at constant temperature, which of the following statements are correct? Choose all that apply. No condensation will occur. The pressure in the container will be 100 mm Hg. Some of the vapor initially present will condense. Only propanol vapor will be present. ✔Liquid propanol will be present.

A 0.470 g sample of a metal, M, reacts completely with sulfuric acid according to M(s) + H2SO4 (aq) →MSO4 (aq) + H2(g) A volume of 217 mL of hydrogen is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 756.0 Torr, and the temperature is 25 \deg C. The vapor pressure of water at 25 \deg C is 23.8 Torr. Calculate the molar mass of the metal.

The vapor pressure of ethanol (C2H5OH) at 19 °C is 40.0torr. A 1.00-g sample of ethanol is placed in a 2.00 L containerat 19 °C. If the container is closed and the ethanolis allowed to reach equilibrium with its vapor, how manygrams of liquid ethanol remain?

A 0.483 g sample of a metal, M, reacts completely with sulfuric acid according to M(s) + H,SO,(aq) MSO, (aq) + H, (g) A volume of 209 mL of hydrogen is collected over water; the water level in the collecting vessel is the same as the outside level. Atmospheric pressure is 756.0 Torr, and the temperature is 25 °C. The vapor pressure of water at 25 °C is 23.8 Torr. Calculate the molar mass of the metal. molar mass: g/mol

Dipalmitoylphosphatidylcholine is a surfactant found in the lining of the lungs. It prevents the lungs from collapsing when the lung volume is low and protects the lungs from injuries caused by inhaled particles. Draw its structure.
