A sample of ammonia gas at 65.5$\degree$C and 524 torr has a volume of 15.31 L. What is its volume when the temperature is -15.8$\degree$C and its pressure is 524 torr?

This is a combined gas law problem. We can use the equation:

(P1V1/T1) = (P2V2/T2)

Where P1, V1, and T1 are the initial pressure, volume, and temperature, and P2 is the final pressure (which is the same as the initial pressure) and T2 is the final temperature.

Plugging in the given values, we get:

(524 torr)(15.31 L)/(338.5 K) = (524 torr)(V2)/257.4 K

Simplifying, we get:

V2 = (524 torr)(15.31 L)(257.4 K)/(338.5 K)(524 torr)

V2 = 11.6 L

Therefore, the answer is B, 11.6 L.
