Question

1. A student calculated the theoretical yield of BaSO4(s) in a precipitation experiment to be 1.352 grams. When she filtered, dried, and weighed her precipitate, however, her actual yield was only 1.279 grams. Calculate the student's percent yield.

Answer 1

Answer:

Student's percent yield =  94.6%

Explanation:

Given:

Estimated yield of BaSO₄(s) = 1.352 grams

Actual yield = 1.279 grams

Find:

Student's percent yield = ?

Computation:

Student's percent yield = [Actual yield / Estimated yield of BaSO₄(s)]100

Student's percent yield = ( 1.279 grams / 1.352 grams)100

Student's percent yield = (0.946)100

Student's percent yield =  94.6%
