0.505l=0.000505m3
20 C=293 K
The gas constant is 8.314 J.K−1·mol−1
Using the idea gas law
PV=nRT
P*0.000505=0.108*8.314*293
Therefore P=520966.76 Pa
Which equals 5.2bar

Industrial deep-sea divers must breathe a mixture of helium and oxygen to prevent a disorienting condition known as nitrogen narcosis. If a diver's tank is filled with a helium-oxygen mixture to a pressure of 170 atmospheres and the partial pressure of helium is 110 atmospheres, the partial pressure of the oxygen is ? - is the question The answer is 60. Total pressure minus the partial pressure= 170-110= 60.
Is helium a liqiud or a solid or gas?
Helium at standard temperature and pressure - is a gas.
What are atmospheres of the gaseous made of?
oxygen and helium
Are hydrogen and helium gases?
They can be depending on the temperature and pressure. They can also be liquids and solids. At room temperature and pressure they are gases.
