Learn how to solve problems like this one with our expert tutor.

Problem: Imagine that you have a 5.50 L gas tank and a 4.50 L 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 145 atm, 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.2C2H2 (g) + 5O2 (g) → 4CO2 (g) + 2 H2O (g)
