Limiting Reactant Problems

Postby Maldonado3K » Sun Apr 08, 2018 11:57 pm

In Lavelle's last Friday example, can someone explain in simpler steps how to solve the last part (finding the maximum yield)?

After finding the limiting reactant, you must look at the ratio of the limiting reactant to the product. Since the ratio is 1 mol CaC2 to 1 mol CaC2, the maximum yield of 1.56 mol CaC2 is 1.56 mol C2H2. Then you multiply this by the molar mass of C2H2 which is 26.038 g/mol.

1.56 mol x 26.038 g/mol = 40.6 g
