    2. A sample of soils was screened and the size separates (smaller than 2mm) were determined,
    along with the following results:
    Sand content (2 0.04mm diameter)

    140 grams

    Silt content (0.05 0.002mm diameter)

    38 grams

    Clay content (<0.002mm diameter)

    22 grams

    Determine the percentage of the total weight of each soil portion, and using the Soil Texture Triangle,
    determine the soil textural class.
