Have to find theoretical yield of recrystallization of acetanilide from water.

1 gram of crude product used (85% acetanilide, 14% Sodium chloride and 1% charcoal)
I got 0.50 grams of purified product.
With percent recovery of : (0.50g/1.00g)* 100% = 50%.
How do I find the theoretical yield?
Please help!!! Thanks is advance

wouldn't it be 1gram*.85 ?

So you had in that 1g of stuff you started with 1 x 0.85 = 0.85g acetanilide; 1 x 0.14 = 0.14g NaCl; 1 x 0.01 = 0.01 g charcoal.

Wouldn't the theoretical yield = 0.85 g acetanilide. That's what you would get if you had 100% yield? right?
I might argue that percent recovery is not 50%. If you recovered 0.50g of acetanilide and you couldn't have obtained more than 0.85 g, that doesn't look like 50% recovery to me.

Thanks a lot, I obtained 0.85 g as well.

Concerning the 0.50g, few crystals were lost during handling.

I re-iterate that the percent recovery is not 50%.

To find the theoretical yield of the recrystallization process, we need to calculate the maximum amount of acetanilide that could be obtained from the given 1 gram of crude product.

First, we need to determine the amount of acetanilide in the crude product. The crude product is composed of 85% acetanilide, which means that 85% of the 1 gram is acetanilide.

Acetanilide in crude product = 85% of 1 gram = 0.85 grams

Since we obtained 0.50 grams of purified product, we can now calculate the percent recovery:

Percent recovery = (mass of purified product / mass of crude product) * 100%
Percent recovery = (0.50g / 1.00g) * 100%
Percent recovery = 50%

Now that we know the percent recovery, we can calculate the theoretical yield using the following formula:

Theoretical yield = (percent recovery / 100%) * acetanilide in crude product

Substituting the values we have:

Theoretical yield = (50% / 100%) * 0.85 grams
Theoretical yield = 0.50 * 0.85 grams
Theoretical yield = 0.425 grams

Therefore, the theoretical yield of the recrystallization process is 0.425 grams.
