A chemist reacted 18.0 Liters of F2 gas with NaCL in the laboratory to form Cl2 gas and NaF. use the ideal gas law equation to determine the mass of nacl that reacted with f2 at 290 k and 1.5 atm

f2+ 2nacl -> cl2 + 2naf

Explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP.
