    im not completely sure if this is correct, but this is what I did. and how I got my answer.

    (3.5 g) / (14.5 + 3.5) g = 0.19 = 19% O by mass

    80.5% - The total mass of the compound is 18g (14.5 + 3.5) then divide the mass of magnesium by the total. easy way to remember is - (part/whole) x 100
