Acetylene torches are used for welding. These torches use a mixture of acetylene gas, \rm C_2H_2, and oxygen gas, O2 to produce the following combustion reaction: 2C2H2(g) + 5O2(g) right arrow 4CO2 (g) + 2H2O(g) Imagine that you have a 7.00L gas tank and a 4.00L 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 155atm , 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. Express your answer with the appropriate units.
