STP is the abbreviation for Standard Temperature and Pressure. The standard temperature is 273 K (0° Celsius) and the standard pressure is 1 atm pressure.
At STP, one mole of gas occupies 22.4 L of volume (molar volume).
You should be able to complete this problem with the Ideal gas law: PV = nRT
P is the pressure of the gas,
V is the volume of the gas,
n is the amount of substance of gas,
T is the temperature of the gas
and R is the gas constant.
