Answer:
P = 0.999375 atm
Step-by-step explanation:
To do this, we need to use the ideal gas equation which is:
PV = nRT (1)
Where:
P: Pressure (atm)
V: Volume (L)
n: moles
R: constant gas (0.082 L atm / K mol)
T: temperature (K)
From here, we can solve for P:
P = nRT/V (2)
Now, we have volume, moles, and temperature. Let's replace them in (2) to solve for P:
P = 0.5 * 0.082 * 273 / 11.2
P = 0.999375 atm
or you can round it to simply 1 atm.
