[CHM 111] Calculating the Density of the Unknown Metal

[Andrew J. Pounds]

Several of you have indicated that you are still having trouble 
calculating the density of the unknown metal.  Here are the relevant 
equations.


Known Quantities:

$\rho_{\mathrm{water}}$ = Density of Water -- look it up based on the 
lab temp that day.

A = mass of empty flask and stopper

B = mass of flask, stopper, and water

C = mass of flask, stopper, and metal

D = mass of flask, stopper, metal, and water



\documentclass{article} \usepackage[utf8x]{inputenc} \pagestyle{empty} 
\begin{document} \rho_{\mathrm{metal}} = 
\frac{C-A}{\frac{B-A}{\rho_{\mathrm{water}}} - 
\frac{D-C}{\rho_{\mathrm{water}}}}} \end{document}


Please let me know if you have any problems reading the equation or if 
you have other questions on how to calculate the density.
