Answer
Moles of O2 = 1.81 mol
Explanation
<em>Given:</em>
moles of Lithium = 7.25 mol
<em>Required</em>: moles of oxygen.
Solution
Step 1: Write the reaction and balance it.
The reaction of Li and O is as follows:
Step 2: Use the stoichiometry to calculate the moles of oxygen.
The molar ratio between Li and O2 is 4:1
Therefore the moles of O2 = 7.25 x (1/4) = 1.81 mol
