Imagine that you have a 5.00 l gas tank and a 3.50 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 135 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. express your answer with the appropriate units. view available hint(s) pp = nothingnothing submit provide feedback next

77.14 atm of pressure should be of an acetylene in the tank.

Explanation:

According to reaction, 2 moles of acetylene reacts with 5 moles of oxygen.

Moles of oxygen=

Moles of acetylene =

Volume of large tank with oxygen gas,

Pressure of the oxygen gas inside the tank =

..[1]

Volume of small tank with acetylene gas ,

Pressure of the acetylene gas inside the tank =

..[2]

Considering both the gases having same temperature T, [1]=[2]

77.14 atm of pressure should be of an acetylene in the tank.

it is b that is the answer.
