Part 1. A chemist reacted 12.0 liters of F222F22 gas with NaCl in the laboratory to form Cl gas and NaF. Use the ideal gas law equation to determine the mass of NaCl that reacted with F at 280. K and 1.50 atm.
+ 2NaCl → Cl + 2NaF
Part 2. Explain how you would determine the mass of sodium chloride that can react with the same volume of fluorine gas at STP.
