B) 0.64 L
C) 1.9 L
D) 6.3 L
E) 20 L

The relationship between pressure and volume for a gas is described by Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume at constant temperature (P1V1 = P2V2). Using this law, we can solve for the new volume (V2) after the pressure change: V2 = (P1V1) / P2 = (1.74 atm * 2.0 L) / 0.555 atm = 6.3 L.
