Imagine that you have a 6.00L gas tank and a 3.50L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 115atm to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.
Acetylene torches are used for welding. These torches use a mixture of acetylene gas,C2H2 and oxygen gas O2 to produce the following combustion reaction:
2C 2 H 2 (g)+5O 2 (g)?4CO 2 (g)+2H 2 O(g)2C2H2(g)+5O2(g) -> 4CO2(g)+2H2O(g)
