Student completes the 'Calculations' section, and is ready to report her 'Conclusions'.

As on previous pages, there is a problem with significant figures.  The calculed molecular weight for the gas in bottle #14 should have been reported as 33.4 g/mol.  Also, this value turns out to be too high and so the student incorrectly identifies the gas.

The 'Conclusion' section is very well written.  It is concise, yet nicely summarizes the major finding made during the lab period.
