Imagine that you have a 7.00L gas tank and a 4.50L 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 105atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time?

i just need to know how to get the temperature, do i assume it is the standard 273K?

    You still feel compelled to use different screen names? It's still confusing to us.
    Yes, 273 will work. Any T will work if you use the same one for both calculations.

Assume ideal behavior for all gases.
