Physics homework: final gas pressure?

A cylinder contains 3.2L of oxygen at 340K and 2.6atm . The gas is heated, causing a piston in the cylinder to move outward. The heating causes the temperature to rise to 650K and the volume of the cylinder to increase to 9.1L .

(pV/T)_a = (pV/T)_b
2.6atm * 3.2L / 340K = p * 9.1L / 650K
p = 1.7 atm
