Answer #1

Succinic acid molecular weight 118.09

Diethyl succinate molecular weight 174.19

hence 118.09 gm of Succinic acid should give 174.19 gm of Diethyl succinate in 100% yield.

hence 10 gm of Succinic acid should give 10 x 174.19 / 118.09= 14.75 gm of Diethyl succinate in 100% yield.

But we observe 8.7 g of Diethyl succinate get produced from 10 gm of Succinic acid

hence 14.75 gm is 100% yield, then 8.7 gm is = 8.7 x 100 / 14.75= 58.98 %

Hence the yield of reaction is 58.98%

Calculate the theoretical yield, actual yield, and percent yield. In the experiemnt conducted 1.04 grams of p-nitrobenzoic acid was added to 30 mL of diethyl ether and then transferred in a seprartory funnel. 15 mL of 5% NaOH was added and the layers were separated. This was done twice to separate the organic from the aqueous layer then vaccum filtration was used to get the salt. I got .12g of salt but I am confused as to how you find...

How to calculate limiting reagent and percent yield? 4-methylcyclohexanol --> 4-methylcyclohexene I used 23 mL 4-methylcyclohexanol and 5 mL of Phosphoric acid. Do we use phosphoric acid to calculate theoretical yield if it is a catalyst? If we do then my percent yield comes out to be like 160% which is wrong because I have to use the limiting reagent which would be phosphoric acid. What do I do? 23mL 4-methylcyclohexanol (.914g/1mL) = 21g 21g (1mol/114.2g) = .184 mol .184...

I need to calculate the concentration (g/mL) of limonene in ethanol in order to calculate the specific rotation. (Observed rotation was 34.65 deg.) We made a solution by adding 2.33g of limonene oil to a 10-mL flask and then filling the flask to the 10 mL line with ethanol. My question is what figures do I use to calculate the concentration in g/mL? Is it 2.33 g limonene /10 mL total volume? Or: I used the known density of limonene...

The following questions involve the reaction of sodium hydroxide and succinic acid. Succinic acid is diprotic: the acid (H2C4H4O4) reacts with two of its hydrogens to give C4H4O42-. The balanced "molecular" equation for the reaction has coefficients of 2 for NaOH and 1 for succinic acid: 2 NaOH (aq) + H2C4O4 (aq) --> Na2C4H4O4 (aq) + 2 H2O (l) A student weights 1.700 g of succinic acid and dissolves it in water in a 250.0 mL volumetric flask.
