To solve this problem, we can use the combined gas law which states that PV/T is constant. We can set up the equation as follows:

P1V1/T1 = P2V2/T2

We can plug in the given values and solve for V2:

(524 torr)(15.31 L)/(65.5°C + 273) = (524 torr)(V2)/(-15.8°C + 273)
V2 = (524 torr)(15.31 L)/(65.5°C + 273) * (-15.8°C + 273)/(524 torr)
V2 = 11.6 L

Therefore, the volume of the ammonia gas at -15.8°C and 524 torr is 11.6 L. The correct answer is B.
