A 4.78-g sample of aluminum completely reacts with oxygen to form 6.67 g of aluminum oxide. Use this data to calculate the mass percent composition of aluminum in aluminum oxide.
Step 1 of 3
Here, we have to calculate the mass percent composition of Al in aluminum oxide.
The mass percent composition or mass percent of an element is that the percentage of the element present in compound’s total mass.
% mass = (mass of element in 1 mole of the compound) / (molar mass of the compound) x 100%
