    The empirical formula is the simplest form of the formula expressed in the lowest ratio. In this case, we just have to divide each subscript by the greatest common factor. Hence.

    a. CN

    b. P2O5

    c. N2O5

    d. NaCl

    e. C9H20

    f. BH3

    g. K2Cr2O7

    h. AlB3

    i. CH

    j. SiCl4
