ANSWER
The amount of sodium oxide to be produced is 49.23 grams
Step-by-step explanation
Given that;
The number of moles of sodium is 1.59 moles
Follow the steps below to find the mass of sodium oxide produced
Step 1; Write a balanced equation for the reaction
In the above chemical equation, 4 moles Na react with 1 mole O2 to give 2 moles Na2O
Step 2; Find the moles of Na2O using a stoichiometry ratio
Let x represents the moles of sodium oxide
The number of moles of sodium oxide is 0.795 mol
Step 3; Find the grams of sodium oxide using the formula below
Recall, that the molar mass of Na2O is 61.9789 g/mol
Therefore, the amount of sodium oxide to be produced is 49.23 grams
