    Answer:

    0.00714 g

    Explanation:

    We know that the volume of one mole of a substance is 22400 cm^3

    Thus;

    1 mole of sulphur occupies 22400 cm^3

    x moles of sulphur occupies 5.0 cm3

    x = 5.0 cm3 * 1 mole/22400 cm^3

    x = 2.23 * 10^-4 moles

    Molar mass of sulphur = 32 g/mol

    Mass of sulphur = 2.23 * 10^-4 moles * 32 g/mol

    Mass of sulphur = 0.00714 g
