At STP, which of the following would have the same number of molecules at 1 L of C2H4 gas? Assume that each behaves as an ideal gas.
A. 0.5 L of H2 gas
B. 2 L of H2O gas
C. 1 L of Ne gas
D. 3 L of Cl2 gas

Respuesta :

Answer: 1L of Ne gas

The answer is Option C , 1L of Ne gas will have the same number of molecules at 1 L of C₂H₄ gas

What is STP ?

At standard temperature and pressure, a system is said to have a temperature of zero degrees centigrade (273 Kelvins) and the pressure equal to the atmosphere is always 1 atm.

Additionally, one mole of any gas at STP occupies a volume of 22.414 L.

This concept only holds true for gases.

So for a gas having same pressure , temperature and moles according to the Ideal Gas Law , volume also needs to be same

                                       

                                           pV=nRT

and in the given option ,Option C has the same volume as that of 1 L of C₂H₄ gas .
