Mixtures of He and O are used in scuba diving tanks to help prevent “the bends.”?
For a particular dive, 46 L He at 25* C and 1.0 atm and 12 L O2 at 25* C and 1.0 atm were pumped into a tank with a volume of 5.0 L. Calculate the partial pressure of each gas and the total pressure in the tank at 25* C. (Temp = 298 K and Gas constant = .0821 L*atm / mol * K)
How in the *** do I figure this out?
PV=nRT
(Pressure)(Volume)=(number of moles)(Gas constant 0.0821)(Temperature in Kelvin)
I think that will work…just plug in the numbers.
Sorry if that doesn’t help….

Blue Steel Faber Low Pressure Steel Tank – 95 cu, 15L $329.95 If you are not using steel cylinders, try to use one and you will soon realize what you have been missing. Faber can offer you the most comprehensive range of cylinders for Scuba Diving. Every year we produce and sell around the world 100.000 cylinders for scuba diving (out of 600.000 in totals). No other manufacturer in the world can match our capabilities and the breadth of our range. Faber Tanks and valves are nitroxready. Cylinders come equipped with a DIN/K type valve that easily converts back and forth depending on the type of First-Stage Regulator to be used in conjunction with the cylinder increasing the versatility of the tank. Steel cylinders are heavier then the same capacity aluminum cylinder. This characteristic has many advantages. The heavier construction allows the diver toremove lead weight from their weight belt or integrated weight system of the BCD, allowing the diver to better distribute weight by moving it to the rear of the BCD a great advantage when wearing a back inflation style (Wing) BCD. Aluminum cylinders as we breathe the weight of air from them create positive buoyancy at or near the end of a dive. The steel cylinder with its negative buoyancy throughout the dive allows you to shed the excess lead that is requiredto keep you properly trimmed while you dive an aluminum cylinder. Faber LP cylinders have a round bottom and come equipped with a cylinder boot. |
