PV = nRT. If the number of moles and the temoerature stays constant, then P1V1 = P2V2.
So, if P1 = 1.0 Atmospheres, and V1 is the unknown, P2 is 3.0 atmospheres, and V2 = 0.52 L, then we have the following relation: 1.0 Atm/V1 = 3.0 Atm/0.52L. It is apparent from this equation that V1, the initial volume, = 1.56L.
