# How do you find theoretical yield of alum?

## How do you find theoretical yield of alum?

Now convert moles of Al to moles of alum using the stoichiometric factor from the balanced chemical equation. You should have found that the reaction could form 0.01750moles of alum (Help Me). Calculate the mass of alum (in grams) from moles of alum. This is the theoretical yield.

### How do you find theoretical yield synthesis?

Multiply the ratio by the limiting reactant’s quantity in moles. The answer is the theoretical yield, in moles, of the desired product.

#### How do you find theoretical yield of Acetanilide?

PROCEDURE

1. 10 g of aniline shall yield acetanilide = 135.16 / 93 × 10 = 14.5 g.
2. Then, Percentage Practical yield = Practical yield / Theoretical yield × 100.
3. = 12 / 14.5 × 100 = 82.75 %

How do you synthesize alum?

In this experiment, you will synthesize a type of alum called potassium aluminum sulfate dodecahydrate, KAl(SO4)2•12H2O. You will synthesize this compound by placing the appropriate ions in one container in aqueous solution and then evaporate the water to form the alum crystals.

How big is the theoretical yield of acetanilide?

Theoretical yield, based on the limiting of aniline (based on the smaller molar mass and the ratio of 1:1 ratio of the two reactants in the balanced equation) is 10.82g of acetanilide. Actual yield was 10.59g acetanilide.

## How much acetanilide can be synthesized in one experiment?

B) THEORITICAL YIELD 0.08 mol 0f aniline x 1 mol of acetanilide x 135.16g = 10.82g acetanilide Therefore, in a perfect experiment, 10.28g of acetanilide will be synthesized.

### What happens if you add too much solvent during recrystallization of acetanilide?

If the student had a perfect lab day he or she would collect 0.160g and have a 100%.percent yield. But the student only collected 0.132g of acetanilide. To get the percent yield, we calculate 0.132g as a percent of 0.160g: Q: What happens if you add too much solvent during recrystallization?

#### What is the reaction of acetanilide with NH2?

Synthesis of Acetanilide Reaction N C O CH3 H NH2+ + CH3 C O C H3C O O H3C C OH O Aniline Acetic anhydride Acetanilide Acetic acid Purpose: Acetanilide is a useful precursor to many pharmaceuticals such as acetaminophen and penicillin. Experimental Procedure. (Estimated time: 1.5 h.)
