The data for question 1 is below: 47g 1. Calculate the number of moles of magnesium (you have a balance in the video that can determine the mass ofmagnesium).2. Then, use stoichiometry (Mg --> H₂) to determine the number of moles of hydrogen gas that should react withmagnesium.3. Hydrochloric acid is an aqueous solution. Therefore, water vapor becomes a factor as well. You will need to subtractthe partial pressure due to water vapor at 25 degrees Celsius from the total pressure to attain the partial pressureof only dry hydrogen gas (Refer to the water vapor chart image above);4. Finally, use PV= nRT to calculate the volume of hydrogen gas. Remember that PV = nRT will calculate "liters" as thevolume.
