Question
1. Calculate the mole ratio of aluminum : hydrogen using your data. How does this ratio compare
with the mole ratio in your balanced equation above? Comment on any experimental errors that
may have effected the experimental mole ratio. 2Al(s)+6HCl(aq)=2AlCl3(aq)+3H2(g)
2. Given that the unknown metal, M, reacts with HCl(aq) to give MCl2(aq), determine the moles of
unknown metal that reacted. Show your work.
3. Calculate the molar mass of the unknown metal and then try to identify the metal using molar
masses of metals in a periodic table. Explain how you arrived at your answer.

Ans 1 - 2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g).
the mole ration of Aluminum and Hydrogen is
2:3
The Aluminium in numbers 2 reaction to form 3 Hydrogen so the ratio of Aluminum : hydrogen is
2:3
