    mass of carbonic acid = 300g

    molar mass of H2CO3 = 2H + C + 3 O

    = 2 x 1.008 + 12.01 + 3 x 16

    = 62.03g/mol

    moles of H2CO3 = mass/Molar mass

    = 300/62.03

    = 4.8364 moles

    1 mole H2CO3 has 3 moles Oxygen

    4.8364 moles H2CO3 contains

    = 3 x 4.8364 moles Oxygen = 14.509 moles Oxygen

    moles = mass/Molar mass

    mass of oxygen = moles x Molar mass of Oxygen

    = 14.509 x 16

    = 232.15g Oxygen

    mass of oxygen in 300g of carbonic acid (H2CO3) = 232.15g
