According to Boyle's Law, at a constant temperature and amount of gas, the pressure and volume of a gas are inversely proportional. Mathematically, this can be expressed as P1V1 = P2V2. Plugging in the values given in the problem, we get (1.2 atm)(1.0 L) = P2(4.0 L). Solving for P2, we get P2 = 0.30 atm. Therefore, the final pressure of the gas is 0.30 atm.
