Question
Solid aluminum and oxygen gas combine in a synthesis reaction. 4.80mol of powdered aluminum is placed into a container with 3.00 mol of oxygen. How many grams of solid aluminum oxide will be formed? What is the excess reactant?
Expert Solution
Step 1
Given,
Moles of aluminium (Al) = 4.80 mol
Moles of Oxygen gas (O2) = 3.00 mol
Mass (in grams) of Aluminium oxide (Al2O3) formed = ?
Excess reactant = ?
Note: molar mass of Aluminium oxide (Al2O3) = (2×27 + 3×16) g/mol = 102 g/mol
