Which gas sample at STP has the same number
of molecules as a 2.0-liter sample of Cl2(g) at
STP?
(1) 1.0 L of NH3(g) (3) 3.0 L of CO2(g)
(2) 2.0 L of CH4(g) (4) 4.0 L of NO(g)

Respuesta :

STP signifies standard temperature and pressure. This conditions are at 1 atmospheric pressure and 0 degrees Celsius. It has been said that at these conditions, one mole of a gas molecule is equivalent to 22.4 liters of volume. Therefore, the correct answer is the second option which is 2 L of CH4.
