    First, we divide the mass fraction of each element by their corresponding molar mass:

    0.52 / 32.1 = 0.0162

    0.285 / 16 = 0.0184

    Next, we simply divide the values that we get:

    0.0184/0.0162 = 1.14

    So, the there are 1.14 times more oxygen atoms than sulfur atoms in the Earth's crust.
