Answer:
0.0135 moles
Step-by-step explanation:
You want to know the number of moles of gas in a 0.325 L container at 1.00 atm and 293 K.
Moles
The ideal gas law is ...
PV = nRT
Solving for n, the number of moles can be found as ...
n = PV/(RT)
n = (101.325 kPa)(0.325 L)/(8.3145 L·kPa/(K·mol)·293 K) ≈ 0.0135 mol
The container can hold 0.0135 moles of gas.
