1. Write out the chemical reaction formula 2. Balance the formula 3. Determine the moles of Al 3. divide by the number of Aluminum atoms used in the reaction and multiply by the number of Hydrogen produced by the moles of Al to figure out the moles of H2 produced 4. Use Ideal gas law to figure out how much volume of hydrogen you have https://en.wikipedia.org/wiki/Ideal_gas_law
