an oxygen tank contains 12.0 L at 25 degree C and 3 atms. After a 4 L canister of oxygen at 25 degree C and 3 atms is emptied into the storage tank, what will happen to the

Question

temperature and pressure of the tank
to be?

Answer 1

Use PV = nRT and solve for n = number of mols n 12.0 L tank initially.
Use PV = nRT and solve for n = number of mols in 4.0 L canister initially.
Add mols, put total into the 12.0 L tank and use PV = nRT and solve for new P. (more mols into same size tank means higher pressure). The problem says the T is the same for both; however, if we place an extra 4L into the storage tank we must do work to do it so the T will rise somewhat.
