What should the mole percent of oxygen be in the diving gas for the partial pressure of oxygen in the mixture to be 0.21 ATM the same as in air at 1 ATM?

0.21 atm / 1.00 atm = 0.21 = 21% This is the same as in normal air!!

Why would the boiling point of water be high in a pressurised deep sea diving bell?
As pressure increases, so does the temperature required to boil. See: http://www.engineeringtoolbox.com/boiling-point-water-d_926.html
Who invented the first oxygen tank?
The first functioning oxygen apparatus for scuba diving was created by Yves Le Prieur in France. The unit consisted of a cylinder of air with a pressure regulator, exhaust pipe and a face mask.
Is nitrogen in a diving tank a solid liquid gas or plasma?
liquid
Why does diving 30m below sea level affect our bodies more than being in a building 30m above sea level?
because water is a much more denser and heavier medium than air. therefore there would be much more pressure asserted on the body in water, than there is in air.
What properties of wood make it useful for diving boards?
the wood of a red willow tree
What is partial pressure of CO2 scuba diving?
Let's start with understanding the question. Partial pressure is defined as the fractional percentage of the gas in the overall gas mixture times the total pressure in Atmospheres. If we assume we're scuba diving using air as our breathing gas, then the fractional percentage of nitrogen is 79% (or .79). Oxygen make up the majority of the balance at 21% (.21) Air is made up primarily of these two gasses. All other gasses that comprise air are considered "trace" gasses. Carbon dioxide is one of these trace gases, and accounts for about 0.039% percent of air by volume. If we assume for a moment that we're at sea level, then the total pressure, by definition, is 1 Atmosphere (atm). This means that the partial pressure of nitrogen in air at sea level is .79. Oxygen is .21. Carbon dioxide is .00039. Every 33 feet a diver descends in sea water adds one additional Atmosphere to the Total Pressure. This means that Total Pressure at 33 feet is 2atm and at 66 feet is 3atm. PPO2 (partial pressure of oxygen) at 33 feet is .42. PPN (nitrogen) is 1.58. PPCO2 (carbon dioxide) is .00078. At 66 feet of sea water PPCO2 is .00117 (.00039 X 3atm).
What is the mixture 15ml of oxygen and 5ml of helium?
A mixture of oxygen and helium is used in diving.
What does nitrogen have to do with diving?
when you go diving, you take a pressurized tank of air, air consists of about 79% Nitrogen and 21% Oxygen, at normal pressure (atmospheric pressuer) the partial pressure of Nitrogen is 0.79 Bar and Oxygen 0.21 Bar which is safe. Under high pressures (say 5 Bar which is at a depth of about 40 metres) the partial pressure of each gas increases Nitrogen (0.79x5=3.95Bar) which causes the lungs to absorb the nitrogen at a higher rate which influences the nervous system causing Narcosis (As if you're Drunk) The reason why you can't take a tank of oxygen instead of air is that oxygen becomes toxic at higher partial pressures
State Dalton's law and Henry's law of partial pressure?
THE DALTON,S LAW OF PARTIAL PRESSURES.Dalton's law is useful to calculate pressure of a gas collected over water in the labouratery.When a gas is collected by downward displacement of water it became moist due to water vapour there for,observed pressure is equal to sum of the pressure of dry gas and the pressure of watervapour[aqueous tension].aqueous tension is constant at a particular temperaturevapour pressure of the dry gas is equal to the difference between total pressure and aqueous tension
What type of pressure is to do with diving?
recreational diving is usually done with 3000 psi of air in a certified SCUBA tank
Why is it important not to hold your breath when diving?
As you ascend from diving the surrounding water pressure decreases. This means if you hold your breath and ascend the pressure on your body decreases so your lungs start to inflate until........pop
Does a partial rebreather mask breath in CO2?
yes but only the ambient CO2 it is a NITROX mask for elevated O2 between 40 and 60 % the rest is AIR which contains Co2 at atmospheric pressure.. 1 BARAdditionAssuming you are talking about some kind of full face diving mask with a regulator attached, you will be rebreathing some gas you have exhaled. So yes, you will be rebreathing CO2 - which will be at a greater concentration as well as a greater partial pressure than the CO2 at atmospheric pressure. But it will be minor amounts. However if you are talking about a hospital type of application then it is a different answer.
How does depth affect pressure?
More depth equals more pressure, thus why ears pop when diving in water.
What is the best definition for a squeeze when its related to diving?
Effects of Increasing Pressure when diving which results in pain or discomfort in your body's air spaces. A squeeze is best defined as a condition that causes pain and discomfort when the pressure INSIDE an air space of your body is LESS than the pressure OUTSIDE an airspace.
What percent of scubadivers live?
All of them: it is very difficult to go scuba diving if you are not alive!
Why are drivers watches pressurised?
So when diving the water pressure cant force its way in
Why is the concentration of helium increased in some gas mixtures that drivers breath in order to reduce patial pressure of oxygen?
The concentration of helium is increased in some gas mixtures to reduce the partial pressure of oxygen because helium is a low-density gas that is less soluble in the blood than nitrogen. By replacing nitrogen with helium, the overall density of the gas mixture is reduced, which helps to decrease the work of breathing. This is particularly beneficial in diving situations, where high pressures can increase the risk of nitrogen narcosis and oxygen toxicity.
