Use the combined gas law:
(P1 * V1) / T1 = (P2 * V2) / T2 but since volume does not change and remains constant, this can be simplified to
P1 / T1 = P2 / T2
Therefore P1 / 234 = 110 / 300
Therefore P1 = (110 * 234)/300 = 85.8 kPa
Since there are 101.325 kPa in 1 atm, then the initial pressure is
85.8/101.325 = 0.847 atm
