Heliox is a helium-oxygen mixture that may be used in scuba tanks for divers working at great depths. It is also used medically as a breathing treatment. A 7.25 L tank holds helium gas at a pressure of 2206 psi. A second 7.25 L tank holds oxygen at a pressure of 586.5 psi. The two gases are mixed in a 7.25 L tank. If the temperature remains the same throughout the process, what is the pressure of the gas mixture...

Name Dalton's Law of Partial Pressures - Many gas samples are a mixture of gases. For example, air is a mixture of gases. The gases dissolved in blood make up a mixture as well. In a gas mixture, each gas exerts its partial pressure (the specific pressure contribution of the gas to the total pressure of the gas mixture). Dalton's law states that the total pressure of a gas mixture (Pita) is the sum of the partial pressures of the...

MODEL 3: PARTIAL PRESSURE Dry air is 78% nitrogen, 21% oxygen, and 1% argon. A percentage is a ratio: "78%" means that out of 100 particles 78 will be nitrogen, or 0.78 as a fraction. Such fractions are unitless. CRITICAL THINKING QUESTIONS 15. Approximately what is the pressure in the room where you are working? (Include the units.) 16. What three gases are causing this total pressure? 17. What fraction (not percent) of air molecules are nitrogen molecules? Oxygen molecules?...
