QUESTION:

The following reaction is stoichiometric as written C4H9Cl 1 NaOC2H5 C4H8 1 C2H5OH 1 NaCl but it is often carried out with an excess of NaOC2H5 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 C4H9Cl, how many grams of NaOC2H5 would be needed to have a 50 percent molar excess of that reactant?

ANSWER:

Step 1 of 2

The given balanced chemical equation is as follows;

From the balanced reaction,

Here,

The ratio is
But you should use a ratio to account for the 50% molar excess.
