At STP, which sample contains the same number of molecules as 11.2 liters of CO2(g) at STP?

1 answer:

8 0

The answer is (3) 11.2 L of N2(g). When the choices are all gases, the number of molecules depends on the molar number of the gas. Under the condition of STP, the molar number of a gas is depends on volume only. So the same volume of gas has the same number of molecules.
