Reason this out.
If PV = nRT, then solve for n.
n for O2 = PV/RT
If P is the same, V is 4L, R is the same and T is the same, then n = constant*V or 4*constant.
So for any other gas at same conditions, what must be true. For n to be the same and the constant is the same, then the 4 must be the same.
At STP 4 liters of O2 contains the same total number of molecules as
1L of NH3
2L of Cl2
8L of He
4L of CO2

1 l of NH3
