According to Charles's law, if the pressure is constant, the volume of a gas is directly proportional to its temperature, so V1/T1=V2/T2. Solving for T2, T2= (V2 x T1)/V1. Plugging in the values, we get T2= (125 mL x 298 K)/350 mL = 106.9 K. Converting to Celsius, T2= -166.1°C, which rounds to -167°C. Therefore, the correct answer is A).

The Volume of 350
