700 grams of an ammonia-water liquid mixture containing 50 wt% ammonia is placed in a close container and heated to 100 °F. A liquid-vapor equilibrium mixture forms at this temperature. Use the lever rule to find the weight fraction of ammonia in the liquid and vapor phases. Find the mass of ammonia and water in each phase.

We put a mixture of helium, oxygen and nitrogen gases in a closed container at 25 ° C. Container pressure in this case is 300 kPa. By a process, we remove all helium gas in the mixture from the closed container. Container pressure in this case reaches 250 kPa. What percentage of the gas mixture did the initial mixture of helium molecules contain? If there are 14 grams of nitrogen and 32 grams of oxygen in this container, what is...
