QUESTION:

The following reaction is stoichiometric as written

\(\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{Cl}+\mathrm{NaOC}_{2} \mathrm{H}_{5} \rightarrow \mathrm{C}_{4} \mathrm{H}_{8}+\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}+\mathrm{NaCl}\)

but it is often carried out with an excess of \(\mathrm{NaOC}_{2} \mathrm{H}_{5}\) to react with any water present in the reaction mixture that might reduce the yield. If the reaction shown was carried out with 6.83 g of \(\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{Cl}\). how many grams of \(\mathrm{NaOC}_{2} \mathrm{H}_{5}\) would be needed to have a 50 percent molar excess of that reactant?
