177 g/s of HCl reacts with 114 g/s of F, to form HF and Cl, in the following reaction: F. (g) + 2 HCl (g) 2 HF (g) + CI, (g) The products are then separated into a waste stream containing 95 mass% HF and 5% CI,. The product stream has a mass flow rate of 200 g/s. What is the mass fraction of Cl, in the product stream
