To solve this problem, we can use the ideal gas law equation:
PV = nRT
Where:
P = pressure
V = volume
n = number of moles
R = ideal gas constant (0.0821 L·atm/(mol·K))
T = temperature in Kelvin
First, we need to convert the initial and final temperatures from Celsius to Kelvin:
Initial temperature (T1) = 23°C + 273.15 = 296.15 K
Final temperature (T2) = 125°C + 273.15 = 398.15 K
Next, we can calculate the initial number of moles (n1) using the ideal gas law equation:
P1V1 = n1RT1
n1 = (P1V1) / (RT1)
Given:
P1 = 0.98 atm
V1 = 6.7 L
T1 = 296.15 K
R = 0.0821 L·atm/(mol·K)
n1 = (0.98 atm * 6.7 L) / (0.0821 L·atm/(mol·K) * 296.15 K)
n1 ≈ 0.285 mol
Now, we can use the ideal gas law equation to find the final pressure (P2):
P2V2 = n2RT2
Since the number of moles (n2) remains constant, we can rewrite the equation as:
P2 = (n1 * R * T2) / V2
Given:
n1 = 0.285 mol
R = 0.0821 L·atm/(mol·K)
T2 = 398.15 K
V2 = 2.7 L
P2 = (0.285 mol * 0.0821 L·atm/(mol·K) * 398.15 K) / 2.7 L
P2 ≈ 10.5 atm
Therefore, the final pressure is approximately 10.5 atm.
