Final answer:
To determine the final pressure of the gas in a container initially at 0.500 atm and 25 ˚C, we can use the combined gas law equation. The final pressure will be approximately 0.664 atm at 125 ˚C.
Step-by-step explanation:
To determine the final pressure of the gas, we can use the combined gas law equation:
P1V1/T1 = P2V2/T2
Where P1 and T1 are the initial pressure and temperature, and P2 and T2 are the final pressure and temperature.
Plugging in the given values:
P1 = 0.500 atm, T1 = 25 ˚C = 298 K
P2 = ?, T2 = 125 ˚C = 398 K
V1 and V2 are not given, so we can assume they remain constant.
Using the equation, we can solve for P2:
P2 = (P1 * T2) / T1 = (0.500 atm * 398 K) / 298 K = 0.664 atm
Therefore, the pressure will be approximately 0.664 atm at 125 ˚C.
