1. An environmental chemist sampling industrial exhaust gases from a coal-burning plant collects a CO2-SO2-H2O mixture in a 29 L steel tank until the pressure reaches 850. torr at 45°C.
If the SO2 concentration in the mixture is 7.91E3 parts per million by volume (ppmv), what is its partial pressure? [Hint: ppmv = (volume of component/volume of mixture) multiplied by 10E6.]
2. What is the pressure (in pascals) of the gas in the flask in the figure below? The picture show a gas flask with h = 3.56cm
3. Liquid nitrogen trichloride is heated in a 2.74 L closed reaction vessel until it decomposed completely to gaseous elements. The resulting mixture exerts a pressure of 739 mmHg at 81°C.
(a) What is the partial pressure of each gas in the container?
nitrogen and chlorine
(b) What is the mass of the original sample?
4. An atmospheric chemist studying the pollutant SO2 places a mixture of SO2 and O2 in a 3.97 L container at 827 K and 1.95 atm. When the reaction occurs, gaseous SO3 forms, and the pressure falls to 1.65 atm. How many moles of SO3 form?
