Part 1. A chemist reacted 12.0 liters of F2 gas with NaCl in the laboratory to form Oz gas and NaF. Use the ideal gas law equation to determine the mass of NaCl that reacted with Fz at 280. K and 1.50 atm. F2 + 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.
