Mols or Temprature was not given so I assumed 70f room and temp.
We know that P = 1 atm, n = number of moles, R = 8.314 J/mol*K and T = (70 + 459.67)*5/9 = 527.67K (converting the temperature from Farrenheight to Kelvin)
so, V = (nRT)/P
Therefore, we need the moles of sulfur hexafluoride gas to calculate the volume. Without the moles of the gas, it is impossible to determine the volume of the gas.
