This is a limiting reagent problem.
1. Write the equation and balance it, at least for the major products (meaning you probably can exclude NaOH, H2O, etc).
2. Convert each to mols
3. Using the coefficients in the balanced equation convert mols of each of the reactants to mols of the product.
The reactant producing the FEWEST mols of the product will the one you use.
4. Using the smallest value for the product, convert mols to g. g = mols x molar mass. That is the theoretical yield (TY). The actual yield (AY) is 0.13 what? grams?
%yield = (AY/TY)*100 =
5. %yield = (ac
Help me find my percent yield for my witting reaction experiment....
The weight of my final product was: 0.13
I put 0.40 g of benzyltriphenylphosphonium chloride, 0.23 g of 9-anthraldehyde and 1.0ml DMF and 0.5ml of aqueous sodium hydroxide into the flask at the start of the experiment
How do I get a percent yield from this data???
8ml of a mixture of 1:1 propanol and water was also added... Idk if that's important
benzyltriphenylphosphonium chloride mol weight is 388.88
9-anthraldehyde mol weight is 206.24
In my book it also says the density of sodium hydroxide 50% is 1.5 gml
After filtration my product was 0.23
My FINAL product was 0.13
