The correct answer is A. 140 atm

Explanation:

We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. We convert the unit Celsius into Kelvin:

0 ° C = 273K, 67 ° C = 273 + 67 = 340K; 94 ° C = 273 + 94 = 367K

P1xV1 / T1 = P2x V2/T2

P2 = ((P1xV1 / T1) xT2) / V2

P2 = ((88,89atm x 17L/340K) x367K) / 12L = 135,927625 atm
