According to Charles's Law, at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin. The initial temperature is 150°C, which is 423 K (150 + 273). The final temperature is 50°C, which is 323 K (50 + 273).

Using the equation V1/T1 = V2/T2, we can solve for V2:

V2 = (V1 x T2) / T1
V2 = (25.5 L x 323 K) / 423 K
V2 = 19.5 L

Therefore, the new volume of oxygen is 19.5 L. The answer is B.
