An experiment was carried out to determine the chemical formula of a metal oxide (MxOy) by burning the metal. The similar experiment but using Magnesium is described in the previous article: "Stoichiometric experiment explained". You can also watch the video for the experiment from the last linked item.

The data from the experiment can be found from this module under "Experimental Data". These are data from two separate groups. Calculate the empirical formula from each group's data. Write a report to make your conclusion about the formula of the metal oxide from each set of experimental data. Answer the questions from this assignment in your report. 

Question 1
Hypothesis

Write a hypothesis to describe the chemical principles of this experiment. You are limited to a 200 words. Do not give goals or experimental steps in your hypothesis.
Status: Not Completed
Question 2
Experiment

Write a description (not a step by step procedure) of the experiment. You are limited to 500 words.
Status: Not Completed
Question 3
Data Analysis

Show your work for the determination of empirical formulas of the metal oxides from experimental data. The molar mass of the metal is 115 g/mol for both groups. You also need to run statistical tests to determine if the two data sets are of the same metal oxide or not.
Status: Not Completed
Question 4
Conclusion

Your conclusion must have discussions about (1) the chemical formula of the metal oxide determined from the two data sets and (2) whether the two groups have the same metal oxides.

Stoichiometry is the study of the quantitative, or measurable, relationships that exist in chemical formulas and also chemical reactions. The calculations of a stoichiometry problem depend upon balanced chemical equations.
