Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 12.0 torr at 35 degrees C. the vapor pressure of pure ethanol at 35 degrees C is 1.00 x 10^2 torr.
A gas mixture contains helium and oxygen at partial pressures of 255 torr and 0.450 atm. What is the total pressure in mmHg after it is placed in a container one-half the volume of the original container?
Calculate the percent yield for an experiment in which 5.50 g of SOCl2 was obtained in a reaction of 5.80 g of SO2 with excess PCl5. Use the following equation:
2SO2 (g) + O2 (g) ↔ 2SO3 (g) A study of this system reveals that there are 4.0E-3 moles of sulfur dioxide gas, and 4.9E-3 moles of oxygen gas present in a 9.0L flask at equilibrium. The equilibrium constant for this reaction is 4.1E-3.
