Percent Yield Lab Report
Instructions: For this investigative phenomenon, you will need to determine the percent yield of
magnesium oxide from the given reaction to determine if it is a useful commercial process.
Record your data and calculations in the lab report below. You will submit your completed
report.
Title: Percent Yield Lab Report
Objective(s):
● determine the percent yield of magnesium oxide from the given reaction to
determine if it is a useful commercial process
Hypothesis:
No hypothesis is needed for this lab. Your theoretical yield calculation serves as your prediction
for what you expect the lab to produce, and that will be determined later in the lab.
Procedure:
Access the virtual lab. Because this lab is virtual, summarize the steps used to collect your data.
Besides, list and explain your controlled variables, independent variable, and dependent variable
for this lab.
Materials:
Percent Yield Virtual Lab
Crucible
Magnesium strip
Bunsen burner
Scale
Variables:
Remember, controlled variables are factors that remain the same throughout the
experiment. An independent (test) variable changes so that the experimenter can see the
effect on other variables. The dependent (outcome) variable will change in response to
the test variable.
Controlled variables:
The temperature of the room
The temperature of the flame
Mass of the crucible
Independent Variable: Amount of Mg

Dependent Variable: the yield of the reaction
Summary of Steps:
First, I will weigh the crucible, then use steel wool to rub the metal strip. When the strip
