This is a stoichiometry problem that involves finding the amount of reactant needed to completely react with a given amount of another reactant, sodium reacts with oxygen to form sodium oxide and has the following balanced chemical equation:

4 Na+O2→2Na2O

To find the number of moles of sodium that will react completely with 3.82 moles of oxygen, we can use the mole ratio from the balanced equation, or 1 mole of O24 moles of Na

Multiplying this ratio by the given amount of oxygen, we get 1 mole of O24 moles of Na×3.82 moles of O2=15.28 moles of Na

This is the number of moles of sodium that will react completely with 3.82 moles of oxygen.
