Explanation:
First, write a balanced equation
#4"Na" + "O"_2 -> 2"Na"_2"O"#
Then multiply the mols of
#("1 mol O"_2) / ("4 mol Na")#
Remember what you want in the answer should be in the numerator and what is given in the question should be in the denominator so it cancels out.
#10 cancel("mol Na") * ("1 mol O"_2) / (4 cancel("mol Na")) = "2.5 mol O"_2#
