Final answer:
To find the pressure inside the container, we can use the ideal gas law equation: PV = nRT. The pressure inside the container is approximately 9.67 atm.
Step-by-step explanation:
To find the pressure inside the container, we can use the ideal gas law equation: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.
First, we need to convert the given temperature from Celsius to Kelvin: 315K = 315°C + 273.15 = 588.15 K.
Now we can substitute the values into the equation: P(2.5L) = (0.45 mol)(0.0821 L·atm/mol·K)(588.15 K). Solving for P, we get P ≈ 9.67 atm.
