The temperature of a sample of argon gas in a 365 mL container at 740. mmHg and 25^$\circ$C is lowered to 12^$\circ$C. Assuming the volume of the container and the amount of gas is unchanged, calculate the new pressure of the argon. A) 0.468 atm B) 0.931 atm C) 1.02 atm D) 1.54 atm E) 2.03 atm

Using the ideal gas law and the relation $ P_1/T_1 = P_2/T_2 $, convert temperatures to Kelvin and solve for the new pressure. The initial pressure is 740 mmHg (0.974 atm), and the initial temperature is 298 K. The final temperature is 285 K. Solving gives a new pressure of approximately 0.931 atm.
