    Explanation:

    Data obtained from the question include:

    Mass of CuS = 9.56g

    Mass of Cu = 6.35g

    Mass of S = Mass of CuS - Mass and Cu

    Mass of S = 9.56 - 6.35

    Mass of S = 3.21g

    The percentage by mass of sulphur in CuS is given by:

    Mass of S/mass of CuS x 100

    Percentage by mass of S = 3.21/9.56 x 100 = 33.58%
