Asample of fluorine gas has a volume of 5.63 l at 14°c and standard pressure. what will be the pressure in atm if the moles of gas and the temperature do not change but the volume is expanded to 9.21 l?

i know that to solve this, it's (pressure x 5.63l) / 9.21l. temperature and moles are constant so we can ignore those. but i don't know what's the standard pressure or what it even means
