The reaction of ethane gas (C ₂ H ₆ ) with chlorine gas produces C ₂ H ₅ Cl as its main product (along with HCl). In addition, the reaction invariably produces a variety of other minor products, including C ₂ H ₄ Cl, C ₂ H ₃ Cl, and others. Naturally, the production of these minor products reduces the yield of the main product. Calculate the percent yield of C ₂ H ₅ Cl if the reaction of 300 g of ethane with 65.0 g of chlorine produced 490 g of C ₂ H ₅ Cl.
