Determining Percentage yield from theoretical yield and actual yield using the limited reactant mol

When benzene C6H6 reacts with bromine Br2 bromobenzene C6H5Br is obtained: C6H6 Br2 C6H5Br HBr a When 30.0 g of benzene reacts with 65.0 g of bromine what is the theoretical yield of bromobenzene? b If the actual yield of bromobenzene is 42.3 g what is the percentage yield? Home work When ethane C2H6 reacts with chlorine Cl2 the main product is C2H5Cl but other products containing Cl such as C2H4Cl2 are also obtained in small quantities.
The formation of these other products reduces the yield of C2H5Cl. a Calculate the theoretical yield of C2H5Cl when 125 g of C2H6 reacts with 255 g of Cl2 assuming that C2H6 and Cl2 react only to form C2H2Cl and HCl.
b Calculate the percentage yield of C2H5Cl if the reaction produces 206 g of C2H5Cl.
