Lab Report: Determining Percent Yield in a Chemical Reaction
Purpose:
To find out the percent yield of copper in the reaction between copper sulfate (CuSO4) and Iron (Fe).
Materials:
Balance
100-mL beaker
250-mL beaker
Bunsen burner
Copper sulfate crystals
Glass stirring rod
100-mL graduated cylinder
Iron filings
Ring stand and ring
Wire gauze
Procedure:
1. Record mass of clean 100-mL beaker.
2. Add 8.0 grams of copper sulfate crystals to beaker.
3. Add 50.0 milliliters of distilled water to the crystals.
4. Put wire gauze on ring on ring stand, …showed first 75 words of 341 total…

Expected yield of copper<Tab/>2.54 g
Percent yield of copper<Tab/>-17.32%
Calculations:
<Tab/>Actual yield of copper = 69.43 g - 67.33 g = 2.1 g
Percent yield of copper = 2.1 g Cu - 2.54 g Cu
