Hi there,
write the lab report about Analysis of a Two-Component Alloy following all the instructions below. Please make sure that you calculations are accurate (watch sig figs). No plagiarism please. Also, answer all the post lab questions that can be found in the lab manual attached.
Lab Report: Analysis of a Two-Component Alloy
Purpose:
- To use the ideal gas law and the production of hydrogen gas to determine the percent zinc and aluminum in an unknown, two component, alloy.
- The lab report should include theory and methodology, keeping in mind you are working with an “ideal” gas.
Skills and Knowledge:
- Expand and improve on your writing skills with respect to formal lab reports.
- Use your knowledge of chemical reactions and two equation, two unknowns, to solve for the composition of the alloy.
Tasks:
You lab report should include:
- Title page
- Objective
- Introduction
- Procedure Reference.(Leave it empty for me)
- Results and Calculations section
- Discussion
- Conclusion
- Post Lab Questions

Lab 9: Two component alloy experiment results. Results from the experiment are presented in the table below. Pictures of what the experiment looked like during the procedure follow.
Trial 1 Trial 2 Trial 3
Mass of weighing paper (g) 0.1031 0.1213 0.1453
Mass of weighing paper and alloy (g) 1.8467 1.1603 1.5790
mass of bottle and water (g) 4758. 4858. 4916.
mass of bottle and water after reaction (g) 3552. 4140. 3925.
Difference in height of levels of liquid (Dh, cm) 11.04 19.26 15.53
“””1″” means level was higher in the starting bottle
“”2″” means level was higher in the ending bottle” 1 1 1
