At 0oC a 1.0 L flask contains 5.0 × 10-2 mole of N2, 1.5 × 102 mg O2, and 5.0 × 10-1 molecules of NH3. What is the partial pressure of each gas, and what is the total pressure in the flask?
Answer to relevant QuestionsGiven that a sample of air is made up of nitrogen, oxygen, and argon in the mole fractions 78% N2, 21% O2, and 1.0% Ar, what is the density of air at standard temperature and pressure? A compound has the empirical formula CHCl. A 256-mL flask, at 373 K and 750. torr, contains 0.800 g of the gaseous compound. Give the molecular formula. a. If the open-tube manometer in Exercise 22 contains a nonvolatile silicone oil (density = 1.30 g/cm3) instead of mercury (density = 13.6 g/ cm3), what are the pressures in the flask as shown in parts a and b in torr, ...An organic compound contains C, H, N, and O. Combustion of 0.1023 g of the compound in excess oxygen yielded 0.2766 g of CO2 and 0.0991 g of H2O. A sample of 0.4831 g of the compound was analyzed for nitrogen by the Dumas ...Consider the following samples of gases at the same temperature. Arrange each of these samples in order from lowest to highest. a. Pressure b. Average kinetic energy c. Density d. Root mean square velocity Some samples of ...
