5.6 L of hydrochloric acid (HCl)
Explanation:
Knowing that we are at the standard temperature and pressure (STP) conditions, to find the number of liter of hydrochloric acid (HCl) we use the next formula:
number of moles = volume / 22.4 (L/mole)
volume = number of moles × 22.4 (L/mole)
volume of HCl = 0.250 moles × 22.4 (L/mole)
volume of HCl = 5.6 L
