An electrolysis experiment is performed on a molten sample of Al$_2$O$_3$ and 13.5 grams of pure aluminum are obtained. What volume of O$_2$ gas is produced by this experiment? You should assume that the gas is collected at 298 K and a pressure of 1.00 atm.

Step 1
The molar mass of Al is 26.98 g/mol and the molar mass of O is 16.00 g/mol. Since there are 2 Al atoms and 3 O atoms in Al2O3, the molar mass of Al2O3 is: (2 * 26.98 g/mol) + (3 * 16.00 g/mol) = 101.96 g/mol Show more…

Hydrogen gas is prepared in a lab experiment. In this experiment, $18.00 \mathrm{~g}$ of aluminum metal are mixed with $25 \mathrm{~mL}$ of $\mathrm{HCl}\left(d=1.025 \mathrm{~g} / \mathrm{cm}^{3}\right) .$ After the experiment, there are $12.00 \mathrm{~g}$ of aluminum and $30.95 \mathrm{~g}$ of a solution made up of water, aluminum ions, and chloride ions. Assuming no loss of products, how many liters of $\mathrm{H}_{2}$ gas are obtained? The density of hydrogen gas at the temperature and pressure of the experiment is $0.0824 \mathrm{~g} / \mathrm{L}$
Determine the volume of hydrogen gas, measured at -100°C and 5 atm, that results when 38.1 grams of pure copper reacts with sulfuric acid. The copper compound product is a copper (II) compound.
