    Answer:

    Empirical formula: CO₂

    Explanation:

    The empirical formula is defined as the simplest ratio of atoms present in a molecule. We must convert the mass of carbon and oxygen to moles as follows:

    Carbon -Molar mass: 12.01g/mol-

    3.0g * (1mol / 12.01g) = 0.250 moles C

    Oxygen -Molar mass: 16g/mol-

    8.0g * (1mol / 16g) = 0.50 moles O

    The ratio of O:C is:

    0.50mol / 0.250mol = 2

    That means the empirical formula is:

    CO₂
