A) 0.702 atm
B) 11.2 atm
C) 1.42 atm
D) 2.81 atm
E) 0.0351 atm

The pressure of the gas decreases inversely with the increase in volume when temperature and moles of gas are constant (Boyle's Law: P1V1 = P2V2). Quadrupling the volume (4 * 49.00 L) results in the pressure being one-fourth of the original (2.81 atm / 4 = 0.7025 atm, rounded to 0.702 atm).
