What is true at STP?

Pressure is 101 atmosphere.
Volume is 4.2 liters.
Temperature is 273.15 Kelvin.
One mole of gas occupies one liter of volume.

Respuesta :

STP stands for standard temperature and pressure. The standard temperature is 273 K (0° Celsius or 32° Fahrenheit) and the standard pressure is 1 atm pressure. Also, at this condition 1 mole of a substance is equal to 22.4 L.Therefore, the first and the third options are the correct ones.
