    Percentage of S = 72.3%

    Percentage of C = 27.7%

    Explanation:

    Given dа ta:

    Mass of carbon = 20.8 g

    Mass of sulfur = 54.4 g

    Percent composition = ?

    Solution:

    First of all we will calculate the total mass of compound.

    Total mass = mass of carbon + mass of sulfur

    Total mass = 20.8 g + 54.4 g

    Total mass = 75.2 g

    Percentage of carbon:

    Percentage of C = mass of carbon / total mass * 100

    Percentage of C = 20.8 g / 75.2 g * 100

    Percentage of C = 27.7%

    Percentage of Sulfur:

    Percentage of S = mass of carbon / total mass * 100

    Percentage of S = 54.4 g / 75.2 g * 100

    Percentage of S = 72.3%

    Total = 72.3% + 27.7% = 100% (so answer is correct)
