A heliox deep-sea diving mixture contains 2.0 g of oxygen to every 98.0 g of helium....
A heliox deep-sea diving mixture delivers an oxygen partial pressure of 0.30 atm when the total pressure is 11.5 atmWhat is the partial pressure of helium in this mixture?
The atmosphere in a sealed diving bell contained oxygen and helium. If the gas mixture has 0.170 atm of oxygen and a total pressure of 3.20 atm, calvulate the mass of helium in 10.0 L of the gas mixture at 23 degrees C. Mass= g
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...
A diver breathes a heliox mixture with an oxygen mole fraction of 0.052. What must the total pressure be for the partial pressure of oxygen to be 0.22 atm?
A mixture of oxygen and helium gases, in a 9.44 L flask at 61 °C, contains 7.69 grams of oxygen and 0.430 grams of helium. The partial pressure of helium in the flask is atm and the total pressure in the flask is atm. back is
To avoid oxygen toxicity and nitrogen narcosis, deep-sea divers breathe a specialized mixture of gas. Describe the mixture. argon and helium nitrogen and helium hydrogen and oxygen helium and oxygen nitrogen and oxygen Determine the mass of water formed when 125 L NH 3 (at 298 K and 1.50 atm) is reacted with 18.9 L of O2 (at 323 K and 1.1 atm). 4 NH3(g) +50 219) - 4 NO(g) + 6H 2009) 13.8 g H20
The partial pressure of oxygen gas in our atmosphere is 0.21 atm. This is the partial pressure at which human lungs have evolved to be able to breathe this gas. A SCUBA diver, will thus still have to breath oxygen at this pressure even when diving way down in the water. If a mixture of helium and oxygen (heliox) in his tank is at a pressure of 7.00 atm, what must the partial pressure be of helium to keep the...
32) A mixture of 40.0 g of oxygen and 40.0 g of helium has a total pressure of 0.900 atm. What is the partial pressure of each gas?
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...
Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends". For a particular dive, 42.3 L of oxygen gas at 25.0°C and 1.25 atm, and 8.00 L of helium gas at 25.0°C and 1.62 atm were pumped into a tank with a volume of 6.00 L at 25.0°c Calculate (in atm) 1. the partial pressure of oxygen 2. the partial pressure of helium 3. the total pressure in the tank at 25.0°C. The tank...
