How many liters of hydrogen,measured at 20°C and 750 torr,are required to react with 55.2 grams of aluminum oxide in the reaction Al₂O₃ + 3 H₂ $\rightarrow$2 Al + 3 H₂O?

Question

Quizplus · Accepted Answer

To find the volume of hydrogen gas required, first calculate the moles of Al2O3 using its molar mass (101.96 g/mol). Then, use the stoichiometry of the balanced equation (1 mole of Al2O3 reacts with 3 moles of H2) to find the moles of H2 needed. Finally, use the ideal gas law (PV=nRT) to find the volume of H2 at the given conditions (20°C and 750 torr).
